Not product recommendations but FOOD recommendations 😂

Okay ladies so my SO works as a delivery and installer, he has no microwave to heat up food. He eats out a lot because of that and all the money is adding up.. any foods you suggest ? He has been wanting me to make him sandwiches ( peanut butter for the morning and bologna for the afternoon ) plus fruit in the side for both. And also salad, here and there. But I'm sure he's going to get tired of eating the same thing everyday so any ideas ?
