This is really easy and tasty, although it's not fermented or sourdough. It's what we had for dinner growing up when we were too busy to cook.
1/2-3/4 lb. whole wheat pasta
2 tbsp. canola, safflower, or olive oil
1 lb. firm or extra firm tofu (not silken), drained well
Salt, pepper, hot pepper, and garlic powder to taste
1 bunch kale, center stalks removed and leaves torn into bite-size pieces
1 jar of your favorite tomato sauce
Parmesan cheese, optional
Bring a large pot of water to boil; cook pasta according to package directions.
