Having single serving meals can be a lifesaver on busy morning. Most people have a microwave at least at work, so if you have heat and eat servings ready you are good.
Got called in on Monday so had to grab a freezer lunch.
I have always cooked, I was that person who could make a meal from an empty fridge. I have lived alone and with large and small families, I have cooked for camps on wood stoves, and in professional kitchens. I have lived and worked all over the west from Montana, to Seattle to Arizona to San Diego. I have traveled, maybe not 'all over the world', yet, and have collected tastes recipes and techniques everywhere, and every one I meet.
