Trying to get health please help.

I'm 14 and I'm trying to lose weight. I'm an extremely picky eater so I don't eat very many foods. So my diet only consists of vegetables in a can and grapes and apples. I want to try to eat salad but the taste of just the salad bothers me. What are some good name brand, vegan, and decent tasting salad dressings? I don't like the normal salad dressing taste or the ranch one. I'm more into "fancy" favors if that makes sense?  Also i never really liked the taste of nuts or anything or the texture of them but what are some good health bars? Just like salad dressing and health bars for beginners? Hope y'all understand. Thanks everyone 😊
