Heat a pan over medium-high heat with 1/2 tbsp olive oil. In a bowl, toss the red onion, bell peppers, and jalapeños with 1/2 tbsp olive oil, salt to taste, and 1/2 tbsp of Mexican spice. Add to pan in a single layer and sauté until it is softened and slightly charred (about 5 minutes). Set aside.
Heat remaining oil in the same pan over medium-high heat. In the same bowl, add shrimp, juice of 1 1/2 limes, honey, salt to taste, and 1 tbsp Mexican seasoning. Toss to coat. Add to pan in a single layer and let cook undisturbed for 1-2 minutes. Flip shrimp and cook additional 1-2 minutes on other side. The shrimp will be opaque when done (minimum internal temperature of 145 degrees F).
In a small bowl, add the corn, black beans, remaining Mexican spice, remaining lime juice, and salt to taste. Since these don't need additional cooking, you can heat them up in a small covered pot over medium heat until they are warmed through or microwave in the bowl for 2 minutes (or until heated through).
Divide the rice, black beans + corn, shrimp, and veggies between bowls and top with salsa, cilantro, and cotija cheese. Serve with lime wedges and enjoy!
