Tomato and yogurt free Pasta sauce ideas please

Getting bored with the sauces i know (egg and quark) Does anyone know any others that do not have tomatoes, fromage frais or yogurt in. No I'm not fussy but have an allergic daughter who can't have tomatoes in the house and yogurts make her sick !!

I often make 'bacon and egg spaghetti' which is like a take on carbonara:
Fry an onion and lean bacon in fry light and boil pasta
When the pasta is cooked, drain it and put it in the pan with the bacon/onion
Pour over beaten egg and stir, using the residual heat from the pan to partly cook the eggs
Serve while the eggs are still slightly wet and add grated parmesan and black pepper

Is it just yoghurt that she can't take or all dairy eg creme fraiche, fromage frais, cream, cheese? Is so then how about some of these?
