I have no idea, although I've yet to meet an omnivore who wouldn't consider pot roast a wholesome, home-cooked meal. And I mean, yes: "radical acceptance" implies "I can live with this situation if I have to." Very few people, or at least very few people who would view the LW as a person with feelings and needs that should be considered, would suggest that she has to put up with a situation that is truly intolerable. If practical compromises like crock pot chili or a large salad with cold protein or anything that can be kept warm in the oven without becoming inedible are rejected in favor of spaghetti bolognese or roast chicken, then that may well be a bridge too far.
