> Burgers and hot dogs require a lot fewer steps to cook them than almost anything with vegetables
You can take just about any vegetable, add salt and pepper and oil, and shove it in the oven, cook it on the stove, boil it, etc... and many vegetables can be eaten raw. Unless you're referring to nuking hot dogs in the microwave, meat and vegetables require the same amount of effort, whatever you're willing to put in.
When I ate steak, my vegetables would cook in the same exact pan, with the same seasonings, for the same amount of time (if you like medium-rare, though personally I ate my steaks blue)
In many cases, probably most, a vegetarian meal is easier to prepare than a burger. And from a health perspective, burgers and hotdogs should not be a daily diet anyway.
> There's not a lot of ready veggies, and they don't keep very well.
Plenty vegetables keep just as long as meat, if you keep them in the same conditions, whether refrigerated or frozen. I've been employed as a cook, waiter, organic farmer, ready-made meal prepper, you name it, I have enough experience in the industry at all verticals that I can definitively tell you that many staple vegetables keep just fine in the period of time between food deliveries.
In the case of ready-made meals, on average, our vegetarian dishes were easier and quicker to prepare, afforded us more versatility in meal designing while keeping prep simple, and they lasted just as long if not longer than meat-oriented meals in our stores.
What I'm really seeing here, and please take no offense, is projection on your part onto the culinary economics of today's world. In fact, many cultures eat primarily vegetarian dishes, and will be the first to tell you how economic and efficient their meals are.
I urge you to reconsider your views as my industry experience, and the experiences of many non-American cultures, simply does not match up with what you're saying. It's good to reduce your meat intake, but spreading this kinds of misinformation about vegetables, even if unintentional, is harmful to the overall goal of reducing our national meat consumption.
