Cook the sausages according to package directions (we use the grill or the oven, and sometimes we cook them in a skillet on the stove) until they are a nice brown color.
While the sausage links are cooking, prepare everything else. Make sure the rolls are cut in half, the tomatoes are sliced, and the lettuce has been prepped. Make the Chimichurri Sauce if desired.
We like to serve Choripán with different side dishes. Our favorite is Ensalada Rusa (which is basically Potato Salad). You can also serve it with chips, grilled veggies, Tomato Onion Salad, or a green salad.
