My ladies started on these at about 11 months:
Dr. Praeger's Broccoli Pancakes
His products are healthy and easy! http://www.drpraegers.com/products/index.aspx
My local grocery store and Whole Foods carries these.
Frozen veggie pancakes (in the Kosher/Organic section)
Frozen berries and add them to Yo Baby Yogurt for a delicious smoothie
Chicken Nuggets (there are some healthy ones out there now, try Earth's Best or there's a Yummy Brand one that we have at our local grocery store).
Kosher section in general has lots of healthy stuff that's tasty, so you don't have to go to a Whole Foods if you don't have one
Amy's Pizza Bites (grocery store or Whole Foods)
