If you were trying to get by without an oven (both the oven and the stovetop didn't work) what appliances (could be several) would you use to replace it? Instapot? Microwave? Crock pot? Adopt a totally raw diet (jk ). Assume you do have a working refrigerator.
(My oven is working. This is not my personal problem, but it is now a practical problem for people I know, and I swear I've encountered this problem before when moving into a new place when it took forever to get gas turned on.)
