Heat oil in 6-quart saucepot or Dutch oven over medium-high heat and brown brisket. Remove brisket to slow cooker.
Cook green peppers in same saucepot, stirring occasionally, until tender, about 4 minutes. Transfer to slow cooker. Stir in sauce, Knorr® Beef flavor Bouillon Cube(s) and garlic.
Cook covered on HIGH 4 to 6 hours or until brisket is fork-tender. Remove brisket from sauce; cool slightly, then shred with two forks. Return to sauce and serve rolled up in tortillas. Serve, if desired, with guacamole, shredded cheese, sour cream or your favorite toppings.
Always allow meat to rest at least 5 minutes after cooking. This will allow it to relax and retain its flavorful juices for these delicious burritos.
