My kids love the croque-monsieurs and readily eat for breakfast. It is ultimately a good compromise for not going to school on an empty stomach, when anything sweet will get to spend out of bed: 2 slices of bread, 1 half slice of ham, 1 slice of Emmenthal cheese and a little butter. With these cooking bags, they can make croque-monsieurs themselves in a toaster, no risk, no extra dishes and very quickly. I find it very easy to use. Convenient also to warm a piece of quiche or pizza still in the toaster! Sold in packs of 2 bags, it helps to have one going, one coming! I love!
