I got this recipe from the newspaper (written by Dawn Lewandowski) a long time ago and still haven't made it.
1 lb whole wheat spaghetti, cooked
1 lb frozen or fresh steamed spinach
1 to 1 1/2 lb firm tofu, in 3/4 inch cubes
2 to 4 T sesame oil
2 to 4 T tamari or soy sauce
2 to 4 t minced garlic
2 T peanut butter
2 T tahini (ground sesame)
2 t sesame seeds
For the sauce:
Pour a Tablespoon or two of sesame oil into a large frying pan or work over medium heat. Add a Tablespoon or two of tamari, a teaspoon or two of minced garlic, 1 tablespoon peanut butter, and 1 tablespoon tahini. Stir until mixed to a thick consistency, about 30 sec.
Immediately add tofu and stir to coat. Stir intermittently, allowing tofu to brown before stirring. When tofu is browned sufficiently, remove tofu from pan and set aside, covering to keep warm.
Repeat the sauce process above, being perhaps a bit more liberal with oil and tamari. Add cooked spaghetti and mix through. Add spinach and mix again. Heat and taste test for flavor. Add tofu when spaghetti is hot. Sprinkle 1 teaspoon sesame seeds. Toss and serve.
(You may use peanut butter rather than sesame oil, omit tahini, add more peanut butter and peanuts, or use only the sesame products. Works well with broccoli and other vegetables as well.)
