In a medium glass bowl, add the shrimp, cumin, garlic powder, paprika, salt and pepper. Toss gently until well coated.
Heat 1 Tbsp of oil in a large skillet.
Add the shrimp and cook on medium-high heat until pink and cooked through, about 4-5 minutes.
Divide cooked brown rice into 4 meal prep containers (1/2 cup each).
Top each with 5 shrimp, then equal amounts of black beans, corn, tomatoes, onion and a slice of lime.
Season to your taste and garnish with fresh chopped cilantro or parsley.
Cover and refrigerate for a max of 4 days.
