There are staples like beans rice oatmeal and eggs that I keep in the house. The grocery sales ad usually comes out on Wednesday, whatever meat is on sale we plan meal prep around. Shop Friday night or Saturday depending on schedules, and cook on sunday afternoons. $100. If we under spend the extra can buy a bonus snack or stay in the envelope for another time. This gives us a little lee way to splurge for celebrations, work parties, and etc.
