In a large skillet, saute shrimp, onion and peppers in oil until pink and thoroughly cooked. Remove shrimp and set aside. Add pasta, 2 ½ cups broth and garlic to the skillet. Bring to a boil then reduce heat and simmer uncovered about 10 minutes until pasta is tender. Add additional broth a little at a time if needed. Taste frequently for doneness. Do not overcook.
Return shrimp to pan and heat thoroughly.
