I have made these for years for my kids. Definitely much cheaper than restaurants. I also just toast some bread instead of biscuits a lot of the time since I always have bread and not biscuits.
I have one child that loves bologna, egg and cheese sandwiches as well. I make these a lot for him because I don't buy bacon unless I can get a really good deal! I just bought 2 packs of 18 count eggs for $5 at Walmart.
