Detox never tasted so delicious. Shrimp is high in protein and very low in fat. Plus, fennel freshens your breath, soothes winter coughs, and can even slim and trim your waistline.
Season shrimp with salt and pepper. Heat 1 tablespoon olive oil in a large nonstick skillet over medium heat; add shrimp and fennel seeds to pan. Cook until shrimp are opaque, turning often (about 3 minutes). Remove pan from heat; toss shrimp with 1 tablespoon lemon juice.
In a large bowl, combine watercress, fennel, radishes, remaining olive oil, and remaining lemon juice, tossing well.
Divide salad among 4 plates; top each evenly with shrimp, mint, and cheese.
