Slow-Cooker Boardwalk Italian Beef Sandwiches - cooking recipe

Ingredients

3 lbs rump roast, trimmed of visible fat
1 medium onion, thinly sliced
1/2 cup water
1 (11 1/2 ounce) jar pepperoncini peppers, sliced (reserve 1/2 cup juice)
1 (2/3 ounce) package Italian salad dressing mix (I use Good Seasons)
2 teaspoons garlic, minced
6 hoagie rolls or 6 hoagie rolls, split
arugula, for serving (optional)
1 tomatoes, sliced, for serving (optional)

Preparation

Place beef and onion in a 3 1/2-quart or larger slow-cooker.
Add water, pepper juice, salad dressing mix and garlic.
If you have time, cover and place in refrigerator to let beef marinate for several hours, turning occasionally.
Cover and cook on low 8-10 hours or until beef is very tender.
Brush cut sides of rolls with some of the cooking liquid.
Transfer beef to cutting board; slice thinly.
Serve on rolls with arugula, sliced tomatoes and sliced peppers.
