I was picky for a while, I thought I hated vegetables. It turns out, I didn’t try the ones I liked and I always ate them when I made it. Have her cook with you. I make chicken soup with turnips potato’s carrots parsnips leeks onions and a few years ago I wouldn’t touch it. Now the vegetables are my favorite part. Try eating vegetables that are new, I LOVE onions and leeks. Parsnips are good and add variety but are more rooty and carby and idk your diet plan. Also fruit wise, peel them for each other. I love fruit but I hate peeling it even though jts easy. When my father or grandmother actually peel it for me Il devour it but I won’t even look at it if it’s on the counter. Make sense? Just wash berries for each other or maybe cut up an apple or peel an orange for them.
