Here is my #1 tip for your leftovers:
If you want to reheat food from the refrigerator, do it on the stove or in the oven. Seriously.
Yes, you’re going to get a pot or pan dirty, but it’s So. Much. Better than the microwave.
The microwave tricks you into thinking it’s easier. Think about it. How many times have you put chili in a bowl in the microwave, set it for :45, then made four trips back to stir it and add time because it’s not hot yet? By the third time the bowl is blazing and you have to get oven mitts to pick it up but the chili is still lukewarm, so you put it on for like 2 more minutes, and then you’re finally done and now it’s nuclear-level hot. And you still can’t eat.
The stove works.
Do the thing that works.
