Have you tried solids yet for them? Since they have teeth they should be ready for more table food. My DS2 is almost 15 months, has 12 teeth, and pretty much eats what we eat. For lunch today he had homemade chicken vegetable soup (with the liquid drained out), part of his brother's pb&j sandwhich, a cheese stick, and a few Ritz crackers. Last night for dinner he had meatloaf, mashed potatos, and green beans.
I still use jarred food on occasion, mostly if we are in a restaurant and I don't have anything else for him, or if he is ready to eat before I finish getting the family dinner cooked. Most nights I put aside a toddler sized portion for him to eat the next day.
You can start with 'soft' foods like buttered bread, small pieces of cheese, very ripe fruit, etc and see how they do.
Some other things DS eats:
green beans/peas/sweet potato/corn
most all fruits
grilled cheese/cheese quesadilla
any kind of chicken or pork
salmon (be careful to check for bones)
deli ham and turkey
mac n' cheese
goldfish/animal crackers/graham crackers for snacks
