Good Eats

I live with my boyfriend and we have his 4 kids’ part time. Raised in western Canada by my European parents (mom from the Ukraine, dad from Hungary) I have a broad pallet. I love to cook, and I love to eat. However, living with the 4 children has made my cooking life an absolute nightmare. They are all very fussy eaters. It has become a struggle to get them to eat anything other than bacon and eggs, cereal or pancakes for breakfast, and for lunch or dinner - pizza, Kraft dinner, hamburgers, or hot dogs. They all hate vegetables and can’t even enjoy the simplest of childhood meals such as spaghetti with meat sauce. I am almost ready to throw in the towel and stop cooking for them all together. If anyone has any suggestions, please help.
