Bring a large pot of water to a boil for orzo pasta.
Crush 2 cloves of garlic and place in shallow dish with about 1/4 cup EVOO along with 1 thinly sliced lemon, red pepper flakes, oregano, chicken or shrimp. Season with salt and pepper, then toss to combine. Heat a large cast-iron skillet over medium-high heat. When meat or shrimp has marinated for 10 minutes, and pan is screaming hot, add chicken or shrimp and lemons. Cook chicken 10-12 minutes, turning occasionally or cook shrimp 6-8 minutes or until pink and firm, tossing with tongs frequently. Squeeze the juice of remaining lemon over pan and serve.
