Yeah, crockpot are great, they can be set to allow you to not have to be in the kitchen all the time to watch the food cook because you can be creative with it for different foods.
Yeah, a lot of these restaurants are overcharging for food cutting corners and adding more salt and sugar and whatever else in those foods people have no clue about which isn't healthy.
So, while I'm not saying you can't eat out but as long as it's not everyday then you should be fine.
