Meal ideas for mechanic shop?

Aimee

We run a small mechanic shop, and there are only 4 of us - no regular "employees," as everyone here is a partial owner to one degree or another. We have a partial kitchen - no oven/stove, but we have a fridge/freezer, microwave, and larger toaster oven. We are trying to cut back on expenses, so I am going to grocery shop for the team instead of us always eating fast food (that we really shouldn't be eating anyways.) What are some things that are easy to stock up on and easy to make as meals that aren't super time consuming? Hard to do with just a microwave/toaster oven. Planning on getting some family size Stouffers meals and stuff, but needing more ideas. Thanks!
