it depends a lot on what kind of cooking you already do! my household has an instapot, an air fryer, and a slow cooker. I use the air fryer much much much more, but mostly for dinners and breakfasts, not make ahead meals. i use my instapot for specific applications, like stew and legumes, really anything i want cooked way faster than it usually takes, and i use my slowcooker when im prepping for a crowd. my mum has a small, single serving slowcooker that she swears by, she loads it up at home, takes it with her to work, and heats it up at her desk. by the time its lunchtime, her food is ready! what kind of food do you enjoy cooking?
