Meat on the other hand is greatly benefited by things like marination, mechanical tenderizing, monitoring temperature as it cooks. You can whip up a steak pretty quick, but probably not any faster than you could stir fry some veggies.
Also in particular, stir frying isn't a great example of a vegetable preparation which is fast. Prep is usually at least twice the amount of time as the frying.
Peanut butter celery sticks would be a better example I think.
There are so many variables it's hard to say anything concrete, but on average I'd bet people spend less active time preparing vegetables to eat than meat.
Maybe with very thin, low quality grocery store steaks. When I eat meat I buy steaks from a butcher that are over an inch thick, and require 5-7 minutes minimum per side for medium rare. Sometimes even more for thicker cuts

A lot of people think vegetables are difficult because they don't have knife skills so it takes multiple minutes to cut a piece of produce. With practice, prep for cooking vegetables should be just as fast. Also, even if it does take an extra couple minutes of my time, its worth it for my own health and morals by not supporting industrialized farming
