You spend enough time at church, you learn to host a lunch.
For the past few years, we've done a lunch for Sunday School teachers before the church year begins. Since it's a 'Back to School' sort of thing, we just serve the sort of things you might pack in a lunchbox.
Sandwiches - assortment of breads, lettuce, tomato, cold cuts, cheese, egg salad, pb&j (as allergies allow).
Fruit, a treat, fresh veggies, maybe some chips.
This year beverages were a choice of milks (fat-free or chocolate), apple juice, or milk.
It's relatively inexpensive, not much time to prep, and most anyone can get something they enjoy.
Clean up is easy, and any leftovers go home with someone who can definitely make use of them.
