I'm not a morning person. So, getting dressed and brushing my teeth is about what I have time for before I have to run (literally) out the door. That makes packing a lunch close to impossible. Therefore I have figured out that the only way for me to bring lunch and save money is to make these that are sort of similar to these:
What you need:
Fry the beef and onions, add tomatoes and spices. Chill
Roll out you dough and spread the goodies. Add cheese and corn and roll up.
Cut in to slices and bake.
Cool and freeze.
Now you can just grab one from the freezer as you scramble for you cell phone on your way out the door.
