Most meals aren't actually a huge time investment if you do them right. Make one trip to the grocery store a week (or two if you really need perishables like milk or fresh fish, but if you do that, just go in & out with a list). Make sure your apartment has a dishwasher. Get a (dishwasher-safe) food processor for chopping & dicing. Clean up while the food is cooking in the oven or on the stove. Cook big batches and have leftovers during the week.

My wife and I spend maybe 3-4 hours/week on cooking, but the key is that it's usually all batched up on Sunday (and maybe Wednesday) nights, so it doesn't interfere with work during the week. On weekdays, it takes 2 minutes to pop a tupperware into the microwave and dump it onto a plate. That's actually a lot faster than ordering Munchery or preparing Blue Apron.
