My suggestion, from living with someone who has nearly identical allergies/sensitivities, is: Black bean soup, lentil soup, thai red curry, hummous/veggies, and kettle black bean chips/chili lime flavors. Check the ingredients on veggie booty (little puffed rice snacky type things). Also Namaste brand mixes for cake and other baked goods might fit the bill (unsure on how they are for yeasts). Good luck.
