My brother is allergic to all things from the animal world and grains ( rice, barely, oats, wheat, rye), cant digest palm oil which cause sever pain , cant have bell pepper or chili and is it for now.
He cant even eat the bog standard vegan food, so I have to figure good food for him.
Chickpea mayo with roasted carrots on teff bread is a favorite for breakfast, dessert home made coconut ice cream with chickpea meringue and chocolate sauce or cocanut toffe sauce ( takes about 40 minutes to make) and dinner, I do far bit of old time yummy food for him, I live in a area where meat wasnt available for all and turnip was the go to food so I have lot of recipes.
But I also have a friend who is allergic to beans, cheese and there was two more things, then a friend who allrgic to carrots and I my self am all allergic to citrus and lactose intolerant and fiber intolerant. Yeah cooking here with friends get interesting but we all can have rhubarb.
