I kind of went the other way, and ditched my toaster oven. I rarely toast anything. And when I do bake, it's usually larger items (pizza, etc.). Although the flatbread pizzas I make nowadays might fit in a large toaster oven, hmm...
As for fridges, I've been living with just a small dorm fridge (no freezer) for a few weeks since my big fridge died. Space gets a little tight, but it's doable for one person. It helps that I vastly simplified my meal plan at about the same time, so there are fewer ingredients to store at one time. The only thing I really miss is the freezer, since I can't buy any frozen food unless I plan to cook it immediately.
