I mean comparing a frozen vegetable patty to a whole frozen meal is a bit of a stretch in quality and affordability imo. Honestly a lot of it has to do with things like how many pans and utensils you use too. Even if I make a burger from ground beef its still only one pan, two cutting boards (one for meat one for veg) and all the fresh produce just needs to be washed and cut, if you wanna grill the onions, same pan no problem, all you need is a knife and a spatula. When I tried to make butter chicken the tastiest recipe called for two different marinades and a sauce you make in stages. I can go over the video and look at the kitchen hardware necessary but I think it's easy to imagine its a lot more. I've found quite a few Indian recipes in particular are similar that way so it seemed topical.
