The importance of balancing your plate

We are big fans of beef in our house. It’s important to make sure your plate is balanced with lots of elements. I love feeding Henry a balanced meal of a powerful protein, like beef, mixed with veggies, dairy, and whole grains. This sandwich has it all in one package!

These sandwiches are packed with veggies like roasted red peppers, pepperoncini, and onion. Adding dairy with the provolone is not only tasty, its nutritious! Top it off with a quality hoagie bun for your grains, and you have a great sandwich for on the go, or an entire meal. 

We paired these Slow Cooker Beef Sandwiches with a simple Strawberry Spinach Salad with Poppyseed Dressing. It was as easy as tossing together fresh baby spinach, crumbled feta, sliced strawberries, and Poppyseed Dressing. Yum!

Can you make the Italian shredded beef ahead of time?

If you need to use up your leftover roast beef, but not ready to eat it straight away, this is the recipe for you! Cook the beef in the slow cooker, let it cool to room temperature and place it in airtight containers or freezer bags. It will keep in the fridge for around three days and it also freezes really well.

If you freeze the beef, thaw it in the refrigerator overnight and then you can reheat it on the stovetop to 165 degrees F. Italian beef sandwiches whenever you want!

Top tips to make this recipe

  • Be sure to remove any excess fat from your leftover roast beef before cooking in the slow cooker.
  • Adjust the amount of pepperoncini if you like it more or less spicy. I used mild, but you can also purchase it spicy if that’s what your family prefers!
