There's a nutritional section here with lots of good, simple foods you can eat.
My favorite lunch/dinner is:
Half can of tuna with a tiny bit of lite mayo.
slices of fresh tomatoe
mozzerella or swiss cheese (don't go nuts)
between two pieces of whole wheat
All toasted in the toaster oven. mmhmm
There's lots of stuff out there that doesn't take a brain surgeon to put together, u just gotta find it.
