Bacon, sausage, kidney or pinto beans, some kind of greens, sweet peppers, onions, and some starch (I think usually manioc root).
I think this recipe is pretty close to what he makes, but I’m not certain. I don’t know what greens he used but I’m pretty sure I would have recognized collards. I looked them up after we got home with the plan to recreate them, but haven’t gotten around to it yet.
Basically it’s supposedly a historic cowboy food from Brazil, maybe of Portuguese origin. Which makes me wonder if the bacon is original or a more recent addition. Anyway, the guys driving the cattle were called tropeiros or “troops” or “troopers”.
