I cook all our food from scratch (aside from the meal or two we eat out each week): breakfasts, lunches and dinners. I also work out of the home, except for one day a week when I work from home. I probably spend 3-4 hours in the kitchen per week, total. On my work from home day, however, I spend about an hour in the morning doing prep and then I rotate roasting, steaming and boiling veggies all day long, and I cook a big vat of rice or quinoa and sometimes stock and something like a crockpot of applesauce. I would say I spend a total of 2-2.5 hours in the kitchen on that day, and then the rest of the week is mostly assembly and a little chopping of fresh fruit, making double batches of smoothies, grilling some chicken... Every couple weeks, I will spend an hour and make something more complex, like a meatballs and sauce or lamb burgers or something, but then I make a triple or quadruple batch and freeze so there is something there when I need it. Also I keep some frozen vegetables (peas, corn, okra for the occasional emergency wednesday when we run out of fresh veggies; all our veggies come in a box to our door on Thursdays, zero grocery shopping other than about five minutes clicking on a computer to make changes each week).
