1/2 yellow squash
1/4 cup ketchup
1/4 cup soy sauce
1/4 cup vegetable oil (olive can be used)
1 clove garlic, crushed
Mix ketchup, soy sauce, vegetable oil, and garlic together for sauce. Cube tofu. Slice yellow squash and zucchini. Marinate tofu, squash, and zucchini in sauce for approximately 5 minutes.
Grill mixture until vegetables are done. (on a George Foreman grill I do 5 minutes, flip, 3 minutes).
Serve over rice. Pour excess sauce over all, if desired.
