Sheet pan dinner: Roasted white fish and cabbage tacos

The dog days of summer are here in the Northeast and it. is. sweaty. I'm hankering for things that are raw or minimally cooked, so a sheet pan dinner may seem counterintuitive. But the cooking here is very quick, requires very few dishes, and the end product leaves us feeling satisfied, but not stupified because being really hot and really full is like entering the third ring of hell.

(As always, skip to the next photo to avoid the toddler update.)

Speaking of hell (KIDDING), we're in that annoying place where the things our kid does seem SO AWFUL to us, but when I tell others about his behavior, I'm usually met with, "Yeah, that sounds about right for a 3-year-old." For instance, I just about blacked out with rage (though I think I handled it okay), when M aimed his stream directly at the back of the toilet instead of into the bowl, effectively spraying our entire bathroom with pee. He thought this was HILARIOUS, while I floated out of my body and burst into a million pieces. The first person I told about this replied, "If he ever has a brother, they'll probably do it together."

Don't get me wrong, it's VERY comforting when other people are completely unfazed by M's behavior. But I'm still left wondering if I'm the world's least effective parent. It can be hard to process.

But I also get it. When I tell someone else about M's behavior that's driving me crazy, to them, it's an isolated incident. But when I'm asking him to put on his shoes for the 20th time after struggling to get him to do five other things in the past hour, that shoe battle feels so much more intense and difficult.

Basically what I'm saying is that 3 has been a tough age so far and that on exhausting days, the last thing I want to do is fight with dinner too (what a segue, huh?).

This dinner is partly steamed and partly roasted. Roasting the fish with the veggies proved counterproductive because a lot of liquid came out of the fish while it cooked, which led to steamed veggies instead of roasted ones. No thanks. 

Instead, you're going to wrap up the fish on a bed of lemon and lime in parchment bundles and let them steam on top of the cabbage and scallions to achieve the best of both cooking methods while still only using one pan. Because, it's hot. Here is a handy illustration of my favorite folding method:

So! Wrap up the fish and let it steam in the citrus. Chop the cabbage and scallions, toss with some olive oil, and throw the whole mess into the oven. While it's cooking, heat some taco shells, whizz some avocado crema in the blender, and prep any other toppings you might want (cheese, tomatoes, jicama, beans, etc). Tonight's dinner can be ready in about 30 minutes and is a nice departure from the usual taco night.

Roasted cabbage fish tacos with avocado chipotle crema  

½ small head of red cabbage, roughly chopped
½ small head of napa cabbage, roughly chopped (about 6 cups total cabbage)
8 scallions, trimmed and cut in half width-wise
2 Tbsp olive oil
1 large lemon
3 large limes, divided
1 ¼ lb cod or other firm white fish (four medium fillets)
1 Tbsp mayo
1 large avocado
Juice of 1 lime (about 1-2 Tbsp)
4-6 Tbsp water
1 small clove garlic
1-2 tsp chipotles in adobo or chipotle hot sauce
1/2 tsp kosher salt
12 corn tortillas

Preheat oven to 400.

Toss the cabbage and scallions with 2 Tbsp of olive oil and salt and spread onto a baking sheet. Set aside.

Slice the lemon and one of the limes. Spread out four sheets of parchment paper or tin foil on your countertop. Place 2 or 3 slices of the lemon and lime in the middle of the parchment. Place one fish filet onto the citrus bed and sprinkle with salt and pepper.

To fold the bundles, bring the edges of the two longest sides of the parchment together and fold over three or four times until you can’t fold anymore without hitting the fish inside. Next, fold the sides toward the middle until you’ve made a tight rectangle around the fish. Place on top of the veggies, making sure to move the scallions out from beneath the fish and toward the edges of the sheet pan.

Roast until the veggies are wilted and lightly browned and the fish flakes easily with a fork, about 15 minutes. If desired, carefully remove the fish bundles, being aware of steam that might escape, and roast the veggies for another 5 minutes.

Meanwhile, make the chipotle avocado crema. Combine the mayo, avocado, lime juice, water, garlic, chipotles or hot sauce, and salt in a blender or food processor and blend until smooth. If too thick, scrape down the sides and add more water a little bit at a time and blend again until you've reached the right consistency. 

Toast the corn tortillas and prep any other fixings you might want with your tacos (cheese, more avocado, beans, tomatoes, etc). Squeeze some more lime juice over the assembled tortillas and serve.

Yield: 4 servings of three tacos and 1 fish fillet each
