Make a meatless meal with tofu! Start with a can of lentil soup, then bump it up with vegetables from the fridge. Or swap the tofu for any leftover cooked chicken, beef or pork you have on hand.
There are several types of tofu you can buy: silken, soft, medium-firm, firm and extra-firm. If using firm or extra-firm, add tofu along with tomato in step 1. If using silken, soft or medium-firm tofu, add with spinach.
