Meatball subs make great football party food. Prepare taco meatballs; then transfer to a slow cooker set on low so they stay warm throughout the party. Add a basket of rolls and some chips, and you’re good to go.
Mix ground beef, bread crumbs and 1 tablespoon of the Taco Seasoning Mix in medium bowl until well blended. Shape into 24 meatballs.
Heat oil in large nonstick skillet on medium-high heat. Brown meatballs; drain fat. Stir in tomato sauce and remaining Taco Seasoning Mix. Bring to boil on high heat. Reduce heat to low; cover and simmer 5 minutes, stirring occasionally.
To serve, line rolls with lettuce. Top with meatballs. Top with assorted toppings, if desired.
Test Kitchen Tip: Add assorted toppings, such as guacamole, sour cream and shredded Cheddar cheese, if desired.
