I need recipes for my mom?

My mom has had her gall bladder surgery a long time ago and some how because of that something happened and she cant eat too much of anything, like sweets, sour, spicy nothing. Al she eats is baked chicken with no flavor and adds some fresh bell peppers, onions, and tomatoes. Or she will eat boiled eggs with no flavoring and milk. And fruits. Thats about it, I NEED RECIPES SO WE CAN COOK FOOD THAT DOESNT HAVE TO BE SO TASTELESS. I NEED EASY FAST COOKING FOODS, OR IT CAN BE JUST advice on how too prevent the BURNING IN HER SIDE IF SHE EATS TOO MUCH of the food listed above (sweet, spicy etc..) AND SHE ALSO HAS ACID REFLEX
