1/2 lb. pasta
1/2 lb shrimp, devained and shelled
1 small can mushrooms, sliced
1 Tbsp. butter
1 Tbsp. flour
3/4 c. milk
few dashes of garlic powder
dash or two of oregano
2 Tbsp. parmesan cheese, shredded
1/2 - 3/4 c. Swiss cheese, shredded (depends on how much you want!)
Cook the pasta according to package directions. Drain and set aside.
While the pasta is cooking, cook the shrimp and mushrooms in a large skillet with the butter over medium heat. Cook about 5 minutes. Add the flour to the skillet, and let it get bubbly (about 30 seconds), then stir in the milk. Add the seasonings. Turn up the heat just a little, and stir constantly for a minute. When the milk has thickened, turn off the heat and add the cheeses. Stir until they are melted in.
Serve the sauce over the cooked pasta. Enjoy!
