Bring salted water to boil, cook orzo 9–10 minutes until al dente, then drain.
Halve cherry tomatoes; mince garlic; pat tilapia dry and season with salt and pepper.
Heat 2 tablespoons olive oil in a large skillet over medium-high and cook tilapia 4–5 minutes per side until opaque; transfer to a plate.
Add remaining oil to the skillet, sauté garlic 30 seconds, add tomatoes and olives, and roast 4 minutes until tomatoes soften; toss in orzo and warm through.
Chop parsley, divide orzo mixture among plates, top with tilapia, squeeze fresh lemon over all, and garnish with parsley.
