Baking/Cooking without an oven

Dear Editor,

A friend told me about your site after my family and I fell on hard times, (we were homeless for about a year…3 kids under the age of 7…2 adults). We are now blessed because we have shelter but the home has no oven, just the burners work on the stove. What is a great way to feed a family of 5 without an oven on the cheap? Also, no freezer here as well, (like I said, thankful for shelter). 🙂 Thank you in advance.
