I'm not really sure what to make, honestly. My gastronomical sensibilities and dietary habits run in a diametrically opposite direction than those of the typical Appalachian family. While I'm notorious for using Paula Deen-esque amounts of butter in my concoctions, I'd nevertheless much rather bring peppered tuna skewers with wasabi mayonnaise to a gathering than, say, deviled eggs or potato salad. I'm trying to compromise. I found a recipe for baked grits with parmesan and black pepper that looks promising (liking grits but refusing to put sugar on them = major Southern street cred), and there is also a cheese straw recipe that sounds pretty tasty (who doesn't like cheese straws?).
I'm not really feeling it for vegetables, as most of the ones I like aren't in season and Matt has informed me that they've already got the requisite green beans, mashed potatoes, and peas-n-onions covered.
I do plan on bringing a dessert: lemon bars. I made my first batch from scratch ever last week, and they were awesome. I'll take just about anything as an excuse to make more. I want to try some with raspberry, but experimentation should probably wait until after I've wowed his grandparents with my mad cooking skillz.
