Potluck Sabbath

We were invited over to a friend's house for lunch after church this coming Sabbath. I asked her what I could bring. "Entree', vegetable, or dessert", she says. So, I offered to bring one of everything :)

I'll be taking my Italian couscous, tiramisu and strawberry pie. What should I take for a vegetable though? Any suggestions? I think I'm stumped...
