In a mixing bowl, combine the shrimp, olive oil, chipotle sauce, lime juice, garlic powder, cumin, salt, and pepper. Toss until the shrimp are well coated. Allow them to marinate for 15-20 minutes.
In a medium saucepan, bring 4 cups of water to a boil. Add the quinoa (or rice) and a pinch of salt, cover, and reduce the heat to low. Cook according to package instructions until done (about 15 minutes for quinoa, 20 minutes for rice).
Heat a skillet over medium-high heat. Add the marinated shrimp and cook for about 2-3 minutes on each side or until they turn pink and opaque (do not overcook). Remove from heat.
While the shrimp are cooking, you can warm the corn and black beans in a small saucepan over low heat, stirring occasionally until heated through (about 5 minutes).
In a bowl, layer the cooked quinoa (or rice) first, followed by a generous portion of black beans and corn. Top with the chipotle lime shrimp, diced avocado, and cherry tomatoes.
Sprinkle fresh cilantro on top and serve with lime wedges on the side for an extra zesty kick.
Notes
Adjust the spice level by varying the amount of chipotle sauce.
