Pat beef strips dry with paper towel; season with salt and pepper.
Heat oil over medium-high heat in large nonstick skillet; cook beef strips for 4 to 5 minutes, stirring, until cooked to medium (160ºF/71ºF) and meat browned but still pink inside. Transfer to a bowl.
Add onion, red pepper and green pepper to the skillet; cook over medium-high heat, stirring often, for 6 to 8 minutes or until softened. Return beef with any accumulated juices to skillet; toss to combine. Remove from heat.
Spread cream cheese all over cut sides of rolls. Use tongs to fill with beef mixture; top with mozzarella.
Wrap each sandwich individually in a large sheet of parchment paper, then overwrap in foil. Warm to serve immediately or store in refrigerator for up to 2 days before warming.
To serve, heat foil-wrapped sandwiches in a preheated 400ºF oven for about 8 minutes until warmed through. To microwave, one sandwich at a time, remove foil wrap, place on a plate and microwave on MEDIUM (50%) power for 2 to 3 minutes or until warmed through. To grill, heat foil-wrapped sandwiches in a closed preheated barbecue over medium-high heat (400°F/200°C) for 6 to 8 minutes, turning twice, or until warmed through.
