I’m in Ohio, and my reluctant suggestions for your meal would be Buckeyes (the chocolate-coated peanut butter candy, not the actual nut), that weird “Cincinnati-style” chili served over spaghetti noodles, and a big buttery ear of sweet corn. “Reluctant” because the idea of eating all 3 in one sitting really grosses me out, let alone in combination with anything else from any other state.
I love your enthusiasm and positivity even more than I love your clever username. I hope you get your epic American meal someday!
