Not much time to make dinner tonight.  I knew I still had half the block of tofu in the fridge.  Also found half jar of pasta sauce from last week.  I figured a 'beefed up' spaghetti would be perfect!  For vegetable, I had nothing fresh that would go with 'tofu marinara,' so looked in the freezer...spinach.
I sauteed onion with the tofu in olive oil and added some spices-- some garlic powder, black pepper, cumin, cayenne, whatever you like.  Then poured the sauce and spinach in. When heated through and pasta cooked, pour the tofu sauce on top!  Done and done :)

As you can see, I had a small amount of bow tie pasta left that I threw in there!
