Even Subway has a veg patty option now..

Really, when a veg option is on the menu.. all vegetarians care about is just veggies it seems.. I imagine there could be hundreds of combinations of veggies that could be had on the menu.. so if you like beets, or tomatoes.. or bell peppers, shitake..

But nope.. restaurants generally just put whatever veggies they feel like.. and consumers just eat whatever the restaurants feel like making up at the moment.. based on the limited selection on the menu..
