What should I make for dinner? (vegetarian)?

My husband is making a pot roast in a crock pot and I don't eat meat (never have), but I'm trying to think of something similar for myself that's vegetarian. I'm thinking something like roasted potatoes... and Idk what else! *And before you ask, NO I don't eat chicken or fish, bc that's not vegetarian! Thanks in advance for any suggestions! :)
