Do you mean what to feed her at mealtimes? I have a dairy allergy so even now when I feed my toddlers I have to remind myself to let them eat cheese, etc! One side-effect of having a dairy allergy in the family is that you learn to make most of your food from scratch, because packaged things often have butter, milk, etc.
Here are some go-to meals that are super easy to make that don't have dairy (for me) and are toddler-friendly (for them):
*french toast (I just use plain egg on Stroehman's 100% whole wheat bread, and the girls dip the strips in unsweetened applesauce -- they LOVE this)
*spaghetti with a bit of tofu mashed in it instead of cheese for protein and calcium
*plain bean burritos (my girls like to dip pieces of plain tortillas or quesadillas in refried beans)
*pita and hummus (some toddlers like hummus, mine don't)
*oatmeal with bananas and chopped raisins for breakfast (can be made with just water, or soy milk)
*couscous with chopped tofu (I get whole wheat couscous from Trader Joe's without the spice pack included. I use two cups of water for one cup of couscous, which is double the water according to the directions because I add about a cup and a half of chopped veggies. I add a little less than a teaspoon each of fresh basil, garlic, blackstrap molasses, a pinch of salt, and a tablespoon of olive oil for flavor. This is an awesome meal, because if you chop just about any veggies small enough -- carrots, broccoli, peas, zuchini, etc. -- and throw them in the pot while the water is getting hot, and also add chopped raisins -- very important!, my kids and my friends' kids seem to eat it no problem. If it turns out flavorless the first time, try adding a little bit more salt, olive oil, or even try adding a bit of apple juice. Add a bit of cheese or pine nuts on your own portion to make it even yummier. Use a food processor to make the veggies faster to prepare. Couscous itself only takes 5 minutes to cook after the water is boiling.
*prepared fish or chicken strips and baked potatoes or sweet potatoes and/or other roasted veggies -- acorn squash and beets are some of my girls' favorites. My one-year old likes the halibut strips you can find at Trader Joe's.
*plain canned black beans, boiled eggs, and sunflower seed butter are good sources of non-dairy protein for a 1 year old. Some of my friends swear by smoothies, which can be made with tofu or soy milk.
*when you are baking, almost any kind of bread, cookie, or muffin can be made with water or soymilk instead of milk, and oil or shortening instead of butter
*look for orange juice, apple juice or soy products enriched with vitamin D. Also, use plenty of dry cereals like Kix or Cheerios to get in lots of calcium and vitamin D. Most soy products have a lot of calcium. Green veggies are good sources of calcium too. So are almonds -- you could try almond butter in sandwiches.
