I gave my children whatever we ate. Because you eat at different times could you save some of what you make for yourself and give it to the babies the following evening? Or, could you eat earlier with them? Your daughter may be more willing to try new things if she sees you eating them. Also, there is no reason they can't eat casseroles. Some food ideas: steamed veggies of any kind, fresh fruit (you can pierce the skin of harder fruit like apples and steam them in a little water in the microwave for 3 minutes to soften-the peels will basically fall right off), tiny pieces of chicken or turkey, scrambled or hard boiled eggs, homemade muffins(my kids love these "cinnamon" muffins: 2 c whole wheat flour, 1/2 c wheat germ, 1/4 c flax seed, 2-3 pears pureed, 2 c pureed steamed veggies such as peas, carrots, spinach, swt potatoes or 6 jars babyfood, 2 tbsp honey, 1 egg, 3 tsp cinnamon, 1 tsp baking soda. Mix together and bake for 15-20mins at 350)
