Picky eater

My 13 month old is such a picky eater it's driving me crazy! And it's frustrating me wasting so much food when things are tight financially right now. He LOVES grilled cheese, peanut butter and jelly, and will eat almost any of the organic fruit/ veggie pouches. How do I get him to keep trying new things? We are constantly having him try new foods over and over again but nothing seems to work. Eggs he simply will NEVER eat, any type of meat he refuses and forget about pasta. He will spit out the pasta instantly.

Any other mamas going through this? Any with suggestions besides "keep offering"?
