In a large bowl, combine the shrimp with olive oil, minced garlic, lime juice, lime zest, ground cumin, chili powder, salt, and pepper. Toss until shrimp are well-coated and let marinate for 10-15 minutes.
While the shrimp marinates, prepare the quinoa. In a medium saucepan, bring vegetable broth or water to a boil. Add the rinsed quinoa, cover, and reduce heat to low. Simmer for about 15 minutes or until liquid is absorbed and quinoa is fluffy.
Heat a large skillet over medium-high heat. Add the marinated shrimp to the skillet and cook for 2-3 minutes on each side or until they turn pink and opaque. Remove from heat.
In a large serving bowl, layer the quinoa as the base. Top it with cooked shrimp, corn, halved cherry tomatoes, sliced avocado, and chopped cilantro.
Drizzle with extra lime juice and season with salt and pepper if needed.
Optionally, garnish with sliced jalapeños, lime wedges, and radish for extra freshness and heat.
