If you're going to a friend's party, all you have to do is take one or a few of these different, easy-to-make, and budget-friendly recipes. They sure are tasty. Just make sure that you bring enough of each because everyone is going to want some. If you're feeling lazy, just take store-bought chips and salsa.
If you're having your own party, my favorite idea for food is to have a nacho or taco bar. That way everyone can pick whatever toppings they want. You can have all different kinds of beans, veggies (tomatoes, onions, bell peppers, jalapenos, etc.) , salsas, and vegan cheeses. Another quick and easy idea is chili or tortilla soup. Throw all the ingredients in your crock pot the morning of and let it cook itself, or make a quick batch on the stove in about a half an hour. The bean burritos are also a delicious option. You could always include them in your nacho/taco bar.
