Tri-Tip Sandwich with Chimichurri Sauce (Tortas de Bistec)
These tri-tip sandwiches with chimichurri sauce are beyond ridiculous. I made them many times for picnics and dinners this summer. Slices of tender and moist beef in a warm toasted bolillo with homemade tangy chimichurri sauce, lettuce, tomato, Oaxaca cheese, and creamy slices of avocado is heaven all in one bite.
