Rinse and drain the black beans if using canned, and set them aside.
Prepare quinoa according to package instructions; once cooked, allow it to cool slightly.
Slice the tempeh into 1/2 inch pieces, and marinate briefly in your preferred spices (such as cumin, garlic powder, and a squeeze of lime). Grill or pan-sear the tempeh until lightly browned on both sides.
Dice the avocado, halve the cherry tomatoes, and chop the red bell pepper into small pieces. If using fresh corn, lightly char it in a pan or on the grill; if using frozen, ensure it is thawed.
In a bowl, layer the cooked quinoa as the base. Top with black beans, grilled tempeh, and the mixed fresh vegetables.
Gently toss to combine the ingredients. Optionally, season with a pinch of salt, pepper, and a splash of lime juice for extra brightness.
Serve immediately and enjoy your vibrant, nutrient-packed burrito bowl.
