Tell the ungrateful savages that if they won't eat what's put on their plate, then they can go to their room with no dessert. Either that, or tie them up in the yard and let them graze.
But seriously, a major factor is attitude, both theirs and yours. There are some vegetarians will who will refuse to eat at the same table as "carnists", at least without lecturing them the entire time. Such people might honestly be better off staying in a hotel and foraging for themselves. On the other hand, there actually are a few cool/reasonable vegetarians in this world--and they might be happy even to get a microwaved frozen veg dinner from the supermarket hippy aisle--if you're honest with them that you were uncertain and wanted to avoid offense.
It may be prudent to clarify what kind of "vegetarians" they really are. Are you sure that they're not vegan? Are they OK with dairy? Eggs? Will they eat fish (which may not be considered meat)? How about shellfish?
If you do want to try cooking, my suggestion is Taco/Burrito Night:
* Tortillas and hard shells
* Rice of your choice
* Refried beans (Goya's are vegan anyway, IIRC)
* Sauteed peppers & onions (cooked in oil)
* Guacamole (bonus points for homemade)
* Shredded cheese, sour cream (assuming that they are not vegan too)
* One or two salsas
* A few sauces (mild, medium, hot)
* For the normals: grilled or sauteed chicken chunks
* For the veggos: browned tofu cubes
Notice that the only last ingredient (the major protein) is a dividing factor; the majority of such a meal would still be a shared experience.
Or if you're a player flush with cash, just tell them to a find a suitable restaurant on Yelp and pick up the bill.
