I pack my lunch to take to work every day. I have my mini frozen meals in the freezer. They are really just leftovers from the nutritious meals I have cooked at home. This week I ate fiesta soup, black beans & rice and lasagna casserole. I pack some veggies, a piece of fruit, and a treat to go with my entree. The treat could be a few animal crackers or a cup of low cal pudding, etc. Usually about 350-450 calories for lunch for me.
I have an insulated lunch bag and the frozen entree keeps the rest of my lunch cold til noon.
