This recipe is sponsored by Target. Let the oven and broiler do the heavy lifting for this super-simple weeknight dinner. Chili powder and cumin give lots of warm spice to bell peppers, onions and shrimp while just a few minutes under the broiler lends a lovely smokiness. Served with warm tortillas and a 3-minute homemade salsa, this is a mostly hands-off meal that's a real crowd-pleaser.
On a large rimmed baking sheet, combine the bell peppers, red onions and sliced jalapeño. Sprinkle with 1/4 cup of the oil, 2 teaspoons of the chili powder and 1 1/2 teaspoons of the cumin. Season generously with salt and pepper and toss well, then spread in an even layer. Roast the vegetables until slightly softened and beginning to brown, about 8 minutes.
Meanwhile, in a food processor, combine the tomatoes, yellow onion, 2 tablespoons of the lemon juice, the coarsely chopped jalapeño, 1 teaspoon of the chili powder and 1 teaspoon of the cumin and process until nearly smooth. Add 1/2 cup of the cilantro and pulse until very finely chopped. Season the salsa with salt and pepper, then transfer to a serving bowl.
Remove the vegetables from the oven. Turn the oven to broil and position a rack 6 to 8 inches from the heat source.
Combine the shrimp with the remaining 2 tablespoons oil, 1 teaspoon chili powder and 1/2 teaspoon cumin in a medium bowl. Season generously with salt and pepper and toss well. Scatter the shrimp over the vegetables and broil until the shrimp are just cooked through, 4 to 5 minutes.
Sprinkle the vegetables and shrimp with the remaining 2 tablespoons lemon juice and 1/2 cup cilantro. Serve with warm corn tortillas and the salsa.
