Savory Shrimp Fajitas

In a small bowl, combine the cumin, garlic powder, pepper, salt, chili powder, brown sugar, and oregano. Put the 1/4 cup of olive oil in a medium bowl and stir in all but 1 Tbs. of the spice mix. Add the garlic and shrimp; toss to coat.

Heat a 12-inch sauté pan over medium-high heat, and, when hot, add the remaining 2 Tbs. olive oil. Add the sliced onion and sauté until they’re softened and fragrant and starting to brown, about 4 minutes. Add the chiles or bell peppers and continue to sauté for 3 minutes. Add the remaining spice mixture and sauté until the onion and chiles are tender but not mushy, another 2 minutes. Transfer to a bowl. Return the skillet to medium high heat and add the shrimp. Cook, stirring frequently, until the shrimp are cooked through, 3 to 4 minutes. Add the sautéed vegetables; toss to combine and reheat. Transfer to a large serving platter. Serve with the warmed flour tortillas, cilantro, lime wedges for squeezing, and sour cream, if using.
