I just discovered that my 6 in nonstick pan fits in the toaster oven! While my first attempt at a makeshift mini-frittata leaves something to be desired, there is great potential there. Today I tried
leftover creamed spinach (1/2 C)
Next time I will probably still mix in some milk or half & half with the egg to make it more tender. Spread the spinach more evenly along the bottom of the pan. Possible addition of leeks, red peppers, bacon, ham. I would probably also advise that the toaster oven preheat beforehand so you don’t get as much browning on the edges (it makes them tough). 375 should do the trick.
