Prepare the base: fluff the quinoa and season with a pinch of salt. If you’re using brown rice, skip the extra salt here.
Season the beans and corn: in a bowl, toss with lime juice, olive oil, cumin, paprika, chili powder, salt, and pepper. Give it a quick stir so the flavors bloom.
Assemble the toppings: slice avocado, dice tomato, chop onion, pepper, and cilantro. Set aside a little extra cilantro for a bright finish.
Layer the bowl: lay down a bed of greens, add quinoa, then pile on beans, corn, peppers, and tomatoes. Top with avocado slices.
Finish with a zing: squeeze fresh lime over everything, sprinkle with cilantro, and add any optional toppings you love. Done—and it looks Insta-worthy without any extra effort.
