One thing my daughter seemed to like was sweet potato. You can even find them in the larger grocery stores sold singly already wrapped in saran wrap to just take home and put in the microwave. Bake until its tender and cut into chunks.
Turkey sausage links (like the brown and serve - precooked) heated and cut into small pieces.
Baked apples done in the microwave with a little brown sugar and cinnamon. Just cut and cool.
Gerber has these yogurt melts that are kind of like meringues. They melt in your mouth and are really yummy.
Scrambled eggs are good as a source of protein, too.
