Hi, our family reunion is in a few weeks.
How about a bean and corn salad? There are tons of super easy recipes like:
-A can of corn-Can of black beans-Can of red beans-Can of chickpeas-Can of any other beans you might like-One onion diced-One red pepper (or another color) diced-Olive oil-Red wine vinegar-Salt, pepper, etc.
I have seen tons of recipes like this and they are always super good, especially with tortilla chips. Mmm, I want some right now, LOL. I think it is pretty flexible--you could add soybeans, soy sauce, chopped garlic, different spices--whatever you like.
Anyway, this would definitely make it through a hot day with no issues as long as you don't add any meat or dairy to it.
I really like this chili pasta bake: http://www.swfinefoods.com/recipes/static/recipe-CHILI-PASTA-BAKE.htm
I use ground turkey instead of beef. The original recipe I have (off of a can of diced tomatoes) doesn't include the corn or black beans. It also just has a can of diced tomatoes and a 7oz can of diced green chilies. You can make it ahead, and heat it at your mom's. (as a side note, I make this and freeze it in loaf pans to reheat for an easy dinner)
Another idea is a black bean and corn salad: http://allrecipes.com//Recipe/black-bean-and-corn-salad-ii/Detail.aspx
I had something like this yesterday, and it was delicious!
Let me know what you end up making! I'm always looking for new recipes!
Here's a couple of different recipes--I like using different kinds of beans though--these two both just use black beans.
One of these has the awesome idea of using frozen corn--it will keep the dish cold for longer if you make it right before you leave.
