I need healthy and creative meal ideas for my son who is 13 months old.?

Though he is in the 80th %tile for length, he's only in the 22nd %tile for weight even though he eats so much. And because he eats a lot (I really don't know where all the food fits in his body), I want to be sure to feed him healthful things. Aside from packaged baby meals, he eats lunch meat, chicken, mashed potatoes, strawberries, avocado (sometimes), peaches, apples, and tons of bread. I have a hard time getting him to eat veggies unless its in a pureed baby food version. I'm really looking for finger foods he can feed himself instead of jarred baby food.
