I don't know of any specific recipes but I know that my husband suffers from gastritis and loves pasta. So, in order to fix his favorite foods without making him "suffer" for it, any time I cook a tomato-based sauce, I add in a tablespoon of sugar to help counteract the acid in the tomatoes. It helps him a lot and he never has a problem now after spaghetti or lasagna. You may want to try looking up foods that can cause gastritis symptoms and see what you find. You may be able to locate ways to counteract those foods and should be able to alter recipes accordingly. Good luck.
