Anything warm is a familiar consistency from their "childhood" I think you may find any warm moist foods with out salt - like Grits, Oatmeal, polenta, cooked rice, mashed potatoes, Cooked grains- Quinoa, Barley, Kamut ect. will all be received happily. You can sneak in some Red Palm oil, finely chopped veggies, shredded unsweetened coconut, chopped nuts or cook with fruit or veggie juices to add more nutrition.
