I have 3, and I'm expected to bring them all, lol.
Appetizer: Incredibly unhealthy chili-cheese dip.
This one is just mixing other products for the most part. I brown some breakfast sausage, then mix it with 1 small jar of Tostino's queso, one can of chili, a drained can of rotel, and mix in a bunch of cumin and add cayanne paper to spice tolerance. Nuke it and stor a few times. Great on chips and makes ludicrous chili dogs.
Entree: pork tenderloin. It's always a huge hit, and it's embarrassingly easy:
Cover it in Soy Sauce and Grill Mates Montreal Steak Seasoning, cook at 350 for 45 minutes, and (this is key) LET IT SIT for 10 minutes before cutting it. Also cut to serve instead of pre-slicing. Those last 2 bits are the "secret" that keeps it from being dry.
Desert: Sopapilla cheesecake. It's basically concentrated diabetes
Layer bottom of 9x13 glass pan with a dough sheet (crescent rolls pinched together also works), mix 3 8oz packages of cream cheese, 1.5 cups of sugar, and a teaspoon of vanilla together and pour over the dough. Polut another dough sheet on top and melt a stick of butter and pour over the top. Mix a teaspoon of cinnamon with another 1/2 cup of sugar and sprinkle over the melted butter. Bake at 350 for an hour then let harden in fridge overnight to set. I like to heat it up a bit in the oven to soften and re-melt to serve.
