Is there not a bowl of leaf vegetables plus additional salad items on the side counter next to the light bites offering? Here's a photo of a vegetarian friendly lunch I took last month (previously shared in this forum).

I'd admit I usually pass on the sauce based offerings. I accept though I maybe one of a minority since the "slop" has been part of the buffet menu for several years now and other customers must be consuming it. Surely Baxter Storey would have replaced it with something else otherwise.
