Do you have a "Whole Foods" near you?

When traveling (with a rental apartment with fridge/freezer), I've been known to go to Whole Foods to their Salad Bar/Hot Bar and pick up multiple trays of food. Then I return to the apartment and put them in the freezer.

Whole Foods doesn't care how many of the containers you take, so you could easily fill them with what you want per meal, then repeat until you have a weeks worth of food. Once you return home, throw them all in the freezer. except the fresh veggies and the meals you are going to eat within 2 days which you put in the fridge.

So ... it's not a Meal Delivery service, it's a meal Pick-up service. But it's the closest I can come up with based on the info you provided.

I enjoy cooking, so I prepare my weeks food on Sundays, then refrigerate/freeze for lunches and dinners.
