To Make the Sandwiches

Notes
Store leftover filling in an airtight container in the refrigerator for up to 3 days. Store sandwich ingredients separately and assemble fresh when ready to serve.
Freeze the filling in a freezer-safe container or bag for up to 3 months, and thaw overnight in the refrigerator before reheating.
Reheat gently in a skillet on the stovetop or in short intervals in the microwave until warmed through.
Leftover filling is versatile and works well for wraps, bowls, and quesadillas.
No need to brown or marinate the meat prior to slow-cooking. The cooking time is shorter than many slow cooker beef recipes to help prevent overcooking.
Beef is most tender and easy to shred when cooked to 205 ℉.
Spoon a little of the cooking liquid over each sandwich before adding the cheese for extra juiciness.
