What is the cuisine in Slovenia & Croatia like?

I am looking at doing a backpacking trip in Slovenia and Croatia in the next 1-2 years. I understand that as coastal countries, especially Croatia, they will have a heavier base of seafood in their food.

I, unfortunately, am very much a landlocked US state gal and don't care much at all for seafood. It makes me sick, which does get annoying.

I expect I'll still be able to survive off of groceries for the most part, but would love to comfortably go to restaurants still without feeling like the dumb tourist who gets the "chicken tenders" version of food.

I love pastas, chicken, beef, vegies. Just no seafood.

So my main question is how much of a hassle is this pickiness of mine in these areas?
