Inexpensive Potluck Recipe?

Inexpensive Potluck Recipe?

I am attending a Mother's Day dinner on Saturday, and it's a potluck. So, my only fee is that I have to make a dish to pass. Anybody have any good recipes that are inexpensive, good for potlucks, and stretch really well? Any help is appreciated.
