The first day of the challenge went pretty well. I added a baked potato to my original menu for the day. My tuna macaroni casserole is pictured below (before baking). It was a little dry but tasted okay otherwise. The ingredients were: one pound of elbow macaroni, one can of tuna, packed in water, about 10 cherry tomatoes, chives and four slices of cheese. I divided the casserole into 5 containers. I'll have this for supper for the rest of the week.
