Garlic Butter Shrimp II

40-50 medium shrimp*, peeled and deveined
1 stick butter
3-4 cloves garlic, pressed
1 medium onion, chopped
8 oz. mushrooms, sliced or quartered
1/2 c. frozen chopped spinach
1 pkg. pasta, your choice of size/shape
Parmesan cheese
cracked pepper, to taste

Prep onion, mushrooms, and shrimp.

Melt butter in skillet over medium heat; add onion and garlic and saute until clear. Reduce heat to medium-low. Add mushrooms and saute. Add spinach and cook until heated through; add shrimp and heat for about 2 minutes.

Cover and remove from heat for 5 minutes for shrimp to warm throughout. Serve over your choice of pasta; top with freshly grated Parmesan cheese and cracked black pepper.

*The shrimp I use is already cooked and frozen - and I wait to buy it until it's on sale. (Brookshire's Food Club brand is the best I've found.) I just thaw it out, then toss it in the skillet a few minutes before cooking is finished.
