Nothing wrong with a big pan of walleye. Maybe just don't coat the fish with cornmeal or whatever and cook it in butter or bacon grease. As for backpacking, you can do pretty well if you are creative. Beef jerky, coconut oil, dark chocolate for a treat, rice noodles and make a creamed coconut curry to go with, butter if it's cold enough, hard cheeses, dry salami or pepperoni, nuts and nut butters, rice cakes or crackers to hold the nut butter, tuna and chicken come in foil pouches now. Even regular white rice can be made backpacking. Just use a pot-cozy (I wrap my pot with extra hats and even my sleeping bag) to finish the cooking process so you don't waste your fuel. You could also invest in a dehydrator and make your own concoctions, but I have found my own skills in that department are lacking. If you are just car-camping, you can bring a cooler and keep all kinds of meats, veggies, eggs, bacon and other things.
