I'm hosting a dinner party next week for a group of about 8-12, and I would love to have a taco bar. I was originally dreaming about making Kenji's recipe for carnitas as the meat filling, but I'm not quite sure how smart it would be to make pork at a dinner party where I don't really know most of the other people all too well. I'm also planning a veggie option. I'm looking for inspiration and recipes for beef tacos, preferably something slow cooked, since I will probably have to make the veggie option right before serving. I was thinking of short ribs or something. I would also love some advice for the veggie tacos as well. I pretty much have the toppings figured out (chipotle slaw, radishes, guacamole, pickles onions).
