Re: HELP me entertain~!
It's enough for a well-rounded meal and more (yummy!). Can people pitch in and bring one of the sides or desserts? That's how we usually do it when entertaining. I'm hosting Christmas this year and assigned DH's mom and sisters one side thing to bring (rolls, drinks, a desserts) to lighten my load a bit. Your meal plan sounds delicious though!
If you are worried you won't have enough food, I would triple the recipe on the easier, cheaper things like tatertot casserole, mashed potatoes, and rolls kind of things...
What are your drinks? I'm a fan of having hot chocolate in the crockpot or one special drink (martinellis sparkling apple cider) or peppermint white hot chocolate and then being low key on the rest (sweet tea, iced water). That's just me though.
