Rinse the quinoa thoroughly under cold water and drain well. Add it to a medium saucepan with the broth, butter, and salt. Bring to a boil, then reduce the heat to low, cover, and cook for about 15–20 minutes, until the liquid is absorbed. Remove from the heat and let it stand covered for 5 minutes before fluffing with a fork. Skinnytaste
While the quinoa cooks, prepare the shrimp marinade. Whisk together 1 tablespoon of olive oil, lime juice and zest, lemon juice and zest, garlic, cilantro, chili powder, red pepper flakes, salt, and black pepper.
Add the shrimp and toss until evenly coated. Cover and refrigerate for about 30 minutes. You can marinate the shrimp longer, but avoid leaving it in the citrus mixture for too long because the acid can affect the texture. The source recipes use citrus-based marinades with garlic, herbs, and chili. Skinnytaste
Heat the remaining olive oil in a large skillet or grill pan over medium-high heat. Add the shrimp in a single layer and cook for about 2–3 minutes per side, until pink, opaque, and lightly browned. Remove from the heat immediately to prevent overcooking. Skinnytaste
To make the dressing, whisk together the olive oil, lime juice, lemon juice, honey, salt, and black pepper.
Divide the cooked quinoa and chopped greens among four bowls. Add the tomatoes, red onion, corn, black beans, and avocado.
Top each bowl with the cooked shrimp and fresh cilantro. Drizzle with the citrus dressing and serve with lime wedges.
