First of all, continue to enforce the fact that they should be eating good food. Because of what I was fed when young, I hate soda, candy, and anything sweet. (well that cheesecake does look nice...) Now to your question.
Do your kids really not want bacon? Or how about finding some cool primal reciples? Or use my (originally dad's) great method of egg making. Here it is.
crack two eggs, mix
slice up a lot of cheese
put about 2 tbsp butter in stainless steel pan
stir with spatula while cooking over low heat
when the eggs are "dry," they're ready
While I know coconut oil would be better blah blah and cheese and butter are dairy so some people think it isn't primal, this is good enough for kids.
