I am going to an appetizer/lunch potluck. We will be traveling by car 2 1/2 hours. Do you have any good ideas, recipes that will travel well in the car and will be safe temperature wise? I can take a cooler. I don't have any thing to keep it hot while traveling in the car, but I will have access to stove/oven/microwave once I get to where we are going. Thanks in advance for any great recipe ideas you have for me!
