It sounds like you don't cook at home that much and that picking up more of those skills would solve all of your problems. It can be overwhelming if you're in the newer stages! I sort of still am lol. But learn 1 dish you like at a time, maybe get a simple vegan cookbook for ideas, or crowdsource easy vegan at-home meals here. If you're a newer vegan and are into faux meats more so than lentils, for example, then shop around a figure out which products you like. (That might also be an easy way of translating known non-vegan recipes/meal ideas to vegan ones)

You live in the country, but don't drive for environmental reasons, yet you are considering using Door Dash? Can we also assume you don't want to face the obvious answer: stockpile or grow food and cook for yourself?

I don't mean to be overly critical, but it sounds to me like you are trying to avoid compromising on both your ideals and modern day expectations, to find a practical solution. Your pre-industrial agricultural ancestor would have spent a week stockpiling food in the root cellar, by scrounging around locally, or going very far to stockpile food. They probably were also farming animals in a significantly more sustainable/humane way, though certainly exceedingly scarcely.

Do you mean the fun stuff like soy curls and doing lines of nooch? Mimicking the gluttonous delights of Thee Burger Dude?

Cook at home. Eating vegan, just don't add anything you can't eat.

I wonder if you could buy some of the raw ingredients to make foods you want. If you bought a bulk thing of soybeans, you could make tempeh and tofu with it. There are lots of recipes for seitan out there as well. What else do you wish was more available to you?
