1 boneless, skinless chicken breast, cut into bite-sized pieces and cooked
1/4-1/2 lb broccoli, washed and cut into bite-sized pieces and steamed
noodles (fettuccini, spaghetti, bow-tie, rotini)
Alfredo sauce

Alfredo sauce
1/2 pkg cream cheese
1/4 C parmesan cheese
1/4 C margarine

Combine sauce ingredients and stir over low heat. Don't let it boil, or it will be grainy. It takes awhile to melt. Top noodles with broccoli, chicken, and sauce.
