It doesn't have to be a fake burger. Just something tasty for a healthy daily dose of vegetables.
For me, soy doesn't qualify. It's one of the most common crops in the world and there's already enough of it in other things I eat.
The thing is, "healthy" is often associated with freshly prepared foods. The non-cooking-yourself option for (hopefully) freshly prepared food would be reasonable usually sit-down restaurants, most of which offer plenty of vegetables because they're cheaper than the main course. And of course, delivery is an option.
(Obviously, "freshly prepared" as framed in opposition to pre-prepared with additives, handling, and ingredient selection focused more on the taste & texture surviving longer term delivery and storage.)
Even if you're unwilling or unable to cook, there are plenty of vegetables that are still delicious and nutritious raw. I suggest baby carrots, tomatoes, avocado, and peppers. If you're willing to microwave, there are a whole host of "microwave in bag" options as well...
How so? On face value this feels like an excuse for simply making poor diet choices. If I'm mistaken, then... cook?
Nobody suggested healthy eating requires one to cook. There's a myriad of places everywhere that serve healthy food, so if you're foregoing veggies, it's your choice. s/cheeseburger/salad/g; done.
