I have found it liberating to take a “portable and modular” approach to our household cooking facilities.
Pictured: microwave oven; deluxe toaster-oven; electric kettle; rice cooker; crock pot; single electric burner.
Not pictured (and rarely used): mini wafflemaker; old-school toaster.
Outdoors we have a couple of mini twig-fired stoves, small charcoal grill, single-burner propane camp-stove, and now (gift from friends) a cute little sterno-fueled “portable campfire” for making s’mores.
Oh, and of course the solar oven!
