I can't have milk so my daughter has a lot of milk free meals. She likes:
-Fried rice - this is my lazy meal. Cooked rice, defrosted frozen mixed veg or leftovers, chopped up cooked ham or chicken and a spoonful of oil. Fry it all up until hot then crack an egg over it and mix like crazy. If she likes strong flavours you can add powdered garlic, ginger, chili powder, black pepper etc. A splash of soy sauce if you like but not much because it's really high in salt.
-Most any sort of stew or hot pot - I usually just throw meat and veg into the slow cooker and it always comes out tasty and soft enough for babies. If you like to use gravy powder or stock cubes just double check the ingredients because oddly enough lots of these contain milk.
-Baked potatoes with beans or tuna mayo (some brands of mayo do have milk in so you'll have to check)
-Cooked chicken in wraps, with a little mild salsa or barbecue sauce spread on the wrap
-Pita breads with hummus, sliced tomatoes and cucumber
-Falafels (if you have a blender, they are super easy to make at home since they are basically chickpeas and onion with mild spices)
-Spaghetti with vegetable sauce and meatballs
- Butternut squash soup with bread to dip (another really easy recipe if you have a blender)
-Couscous with beans, sweetcorn, cherry tomatoes and some flaked fish
- Tuna fish cakes - just tuna, leftover veg and mash made into patties and baked (since you're already making milk-free mash)
-Omlettes - just skip any dairy in the recipe and add any veg she likes.
-Stir fried noodles
-Baked fish with sweet potato chips or wedges
-Curry - I use a mild curry paste plus tinned tomatoes and some coconut milk to make it creamy, along with just about any meat/veg combo you like.
Has the doctor said whether she can have almond or rice milk as a substitute? It doesn't taste great but it will give you more options to use in cooking.
Hope something in there is helpful. Let me know if you need any recipes I have tons more.
Edit: found this site with some ideas too.
