Preheat the oven to 425 degrees F. Prep a baking sheet (line with foil or spray with nonstick spray!) to use for the recipe.
In a bowl, whisk together the olive oil, lime juice, zest, honey, cumin, chili powder, paprika, salt, pepper and garlic.
Place the peppers and onions on the baking sheet. Add half of the marinade and toss them well, until they’re all covered. Stick the sheet in the oven and roast for 15 to 20 minutes, tossing once or twice during cook time.
In the meantime, place the shrimp in a bowl and pour the remaining marinade over top. Let sit until the peppers are roasted! In this time, you can make the crema.
Once the peppers are finished, toss them a few times and scoop them over to one side of the pan. Place the shrimp on the sheet in a single layer. Roast the shrimp for 6 to 8 minutes or until it’s just pink and opaque.
Once the shrimp is finished, assemble your fajitas! Start with peppers and onions, add on the shrimp. Drizzle with the crema, sprinkle with cotija cheese and top with pickled onions and fresh cilantro if you wish.
