I haven't read all four pages yet, but I would only eat one meal a day too if needed. My daughter's health will always come first. The only difference between a DUmmie and myself, is that I would not bitch about it on the internet. There are thousands of recipes on the internet that are delicious and the ingredients are cheap. You can feed your family of three for less money than you think.
My meal situation is 1 1/2 or 2 if I am lucky. For lunch, I have a grilled cheese and for dinner, I have a honey ham sandwich or a microwavable pita thing from Stouffers. I'm not much of a breakfast person.
