Veggies (if you need to cook them, make sure they are super, super soft and mushy): carrots, potato/sweet potato chunks, green beans, broccoli, cauliflower, avocado, diced tomatoes, squash chunks, etc.
Fruits: any fruit cup because it is convenient (just drain the syrup and rinse), bananas, cut blueberries, soft pears, soft peaches, mango, etc.
Legumes: beans! kidney, white, black, etc. just make sure they're mushy
Other finger foods: put cheerios or other cereal in a bowl of milk to soften it up, pancakes, any of the Morningstar Farms veggie cakes/patties (they practically fall apart when cut anyhow), pasta with or without sauce, finely ground beef or turkey
Have fun with it! One of my favorite meals to make was pasta primavera - cook frozen mixed veggies, whole grain pasta, and choose either marinara sauce or gravy, then add little meatball chunks or ground beef/turkey. I'd make up one big batch on a Sunday and then portion out enough dishes for the week so all I would have to do is pop it in the microwave each meal. I'd serve with a side of fruit and you've got a great, balanced meal!
