Picky eaters

So my one year old daughter, is a picky eater. I try to make her taste different foods and try different things in moderation but when it comes to like biscuits and gravy she won't eat even though she loves it. She makes herself vomit if she doesn't like it instead of spitting it out. All she wants is dry cherrios and her shakes that help her gain more weight. I don't know what else to give her. Kinda limited on space for fridge. Still currently living out of a mini fridge. So anything that doesn't have to be refrigerated would be best.
