How about fruit smoothies with veg thrown in, peanut butter sandwiches for protein, chilli with beans and tvp, pasta with vegetable-rich tomato sauce? I am basically the grown up version of a 12-year-old picky eater, and I love all these things. You could try black bean burgers with tomato, lettuce, onions and pickles. Baked carrot or sweet potato fries. Mac n cheese with some broccoli mixed in. I find it's helpful to cut vegetables into very small pieces. Are there any vegetables she genuinely enjoys? I know that I struggle with leafy greens but can't get enough peppers and onions... Maybe find what she likes and work that into as many meals as possible.
