Tri Tip Sandwich Recipe with Caramelized Onion, Blue Cheese Relish

Yes, you can make a tri tip roast to slice and serve on a sandwich for your midweek meal. If you choose to make a tri tip sandwich recipe, the versatile cut that’s small, ranging from 2-5 pounds, cooks very quickly compared to other roasts. A bonus is that this type of roast is affordable. Part of the preparation for this dish can be done in advance. You can season your roast the night before or in the morning. You can also prepare the caramelized onions and relish in advance and keep in the fridge. If you do, reheat the mixture a bit before topping your sandwich so that the juice of the relish melts into the meat and over your crusty roll. Once you make this sandwich, you’ll skip the pricey steak sub and be able to enjoy cooking your own gourmet version at home.
