I was going to say the BBQ lil' Smokies, I have a chili dip recipe is made in a crock pot--no reason can't be switched to a warming dish for serving. I also have an Italian meatball recipe from my girlfriends Italian grandmother, that maybe you could reduce to bite size and serve with bite size garlic bread pieces. Crab rangoons
PM me if you or anyone else is interested in the recipes.
Again--Your horse is gorgeous! My mare is 27 yrs. old I have had her since birth and she is doing super for being a "senior senior".
