I've gotten pretty good at frugal cooking in many ways. However, I am about to switch roommates.
My soon-to-be-roommate generally does not cook, preferring to eat out at restaurants or get take out. When I go to his house, his fridge often has food that has gone bad. He is not super frugal in general, and is often too tired to cook at night (he is comfortably self-employed, so there's no job he would ever want to quit).
I know he wants to cook more, though - he's very open to it, and cooks with me when we spend time together. He also signed up for one of those ingredient delivery boxes ($5/meal), which at least is teaching him to cook when I am not present. How can I make the transition to frugal cooking easier for him so that it isn't a shock to his system when we move in together?
Steps I have already taken - showing him that we can freeze chicken in marinade for easy and delicious defrosting (a move that got much acclaim, and the announcement that we should do this all the time); explaining how easy it would be to buy the delivery box ingredients in bulk so that we could make the tasty dishes all the time; offering the use of my slow-cooker so he could cook in the mornings when he is energized....
Does anyone else have tips and tricks for making the transition to frugal cooking easier for someone?
