If you can, I'd suggest preparing phase 1 foods for everyone. If you like wings, there's a recipe for Buffalo Bites somewhere in the recipe discussion area that you could try.
There are lots of phase 1-appropriate versions of pizza, but you could also try any other Italian dish with tomato sauce and cheese (if it's the kind of situation where you'll be able to eat off a plate with utensils). For example, there are a couple of kinds of veggie lasagnas that are very tasty.
You might also consider a pot of chili, maybe with some chopped onions and LF shredded cheese (or regular cheese for them if that's what they like) that can be sprinkled on top. Make it with lean meat, but you can add some healthy oil to it if you want, so it tastes like your guests will be expecting.
If you know someone else is going to bring wings and pizza, you could make one or more of the dishes I mentioned, refrigerate most of it, and leave a couple of servings out for yourself. It would also be a good idea to supplement your meal with some veggies, such as a salad or maybe a broiled tomato, or whatever else you like.
In place of the beer, you might have iced tea or a diet soda. (Iced tea or diet ginger ale can look similar to different kinds of beer, if that matters to you.)
Finally, although you'll be able to eat good food, I recommend you focus on enjoying the company. Too often we focus on what we're eating, and not enough on the people we're with.
