The kitchen in my house has a toaster oven tucked into one corner just under the wall cabinets. It gathered dust unused for years, because toaster ovens were a silly 1970s fad that disintegrated in the face of inexpensive microwave ovens. But I’ve found exactly one use for it that a microwave doesn’t emulate well.
Improvised garlic bread:
Your main prerequisite for this is a loaf of Italian or French bread. Works best if the loaf is more or less baguette-shaped so you can cut the bread into relatively small rounds surrounded by crust.
(1) cut the bread into thick slices,
(2) shave thin slices of butter off a stick of it and lay them on the bread slices until they roughly cover each one
(3) sprinkle garlic powder liberally on top of the butter
(4) place on tinfoil in toaster oven
(5) toast for 2 minutes.
Notably, this works OK even if the bread is a bit old, as the butter moistens it nicely.
Total prep time about 5 minutes. Results: Om nom nom.
That is all.
