I read the reviews beforehand and so added extra kasha/greshka; about a cup. I also used fresh diced tomatoes, pepper paste, an ancho chile, and some tomato paste. I used celery instead of green pepper and didn't use the veggie stock at all. It ended up being thick and chunky, and could serve 4 people easily. Great recipe!
I would agree with the other reviewer, it does make enough for four servings. We loved the flavor of it, but found it to be a little watery for our taste. I even let it boil down a bit. Had i known that it would serve so many, i probably would have added some more beans or kasha to make it a bit thicker.
So easy and so good! I would say that this recipe makes about 4 servings, but I'd still consider doubling it next time I make it. Mine was a bit too spicy, but I'd bet this was because my chili powder is a little hotter than most (still, if you don't like really spicy food, you may want to reduce the chili powder). I used sherry instead of red wine (I didn't have any); otherwise I followed the recipe closely. Highly recommended!
