I've been asked to bring a Mexican dish to a party this weekend, being held by some of my boyfriends' coworkers. The party is not being held at a house and will be about an hour drive from where we live. I do not know what, if any, facilities will be available to use for reheating. I would prefer to bring a dessert, but my boyfriend keeps forgetting to ask if this would be okay with our hosts. I'm not terribly familiar with Mexican food, so I'd love some suggestions! I have texture issues with refried beans, so I would prefer to avoid making something that includes them.
