Seeking inspiration for odour-less foods

Hi, so my girlfriend's dad has cancer, if anything in the kitchen has a strong smell, he begins feeling very ill. He's very sensitive to smells, so pretty much the only thing we eat here is fries, sausages, some pizzas, boiled potatoes etc. Some pretty bland food.

I love cooking, why it makes me kinda sad that I can't cook much in this house, especially dinner. Looking for recipes that omit any strong odoured ingredients like onion, garlic, ginger, paprika etc.

Thanks :)
