There are tons of premade, microwaveable foods at any US grocery store. I like frozen burritos, for example. Some are quite tasty, some quite healthy. Optimize to your preferences. Cooking/cleaning effort is similar to delivery. Price is maybe 30% (that's a guess)

Delivery services add so much cost that I never use them. With trivial effort, I can stop on the way home, and pick up from a restaurant on the way, for half the price, and fewer mistakes.

Consider long term health cost. Are you eating from healthy restaurants? The consequences of a bad diet dwarf all the other costs, which is why learning to meal prep efficiently is probably the best option, long term.
