-something with eggs (frittata, scrambled, quiche)
-something with carbs (overnight French toast, waffles, coffee cake, pancakes, bagels with cream cheese and fixings-- but the casserole type things like overnight French toast are easiest)
-fruit salad
-meat (sausage links, bacon, being mindful of many friends who don't eat pork- so usually turkey / chicken variety of those things)
-coffee / tea / juice
It's actually my favorite meal to host. I feel like it's the easiest meal of the day to get everything timed right, especially if any of the above are cooked in one pan and served out of that pan.
