i usually cook beans and/or lentils and add some diced fresh veggies like tomatoes (sometimes dried tomatoes too), peppers, celery, seitan, sometimes i cook it first and then put it in a saucepan with onions, garlic, veggies (zucchini go nice with lentils), add some olive oil and stew it.
i also like to add some black pepper, chili or curcuma, mmm.
hope it helps!
