In a group of guests coming to my home will be one who observes a kosher diet. 1) Will she be able to eat any food in my house? 2) If she can, I am confused about what I can serve. Eggs are an animal product---do they count as meat, not to be mixed with milk? I want to serve a vegetarian quiche with eggs, milk, and cheese in it and the pastry with vegetable fat and no butter. ??
