Heat the olive oil in a large 12-inch skillet over medium-high heat.
Add the frozen quick steak pieces and cook undisturbed for 2 minutes to brown the first side.
Flip the steak pieces and cook for another 2 minutes until browned and no pink remains, keeping pieces large.
Using a slotted spatula, transfer the cooked steak to a plate, leaving some fat in the skillet.
Add the diced onion and green bell pepper to the skillet and cook for 5-6 minutes until golden and tender.
Stir in the cream cheese and cook until melted and combined with the vegetables.
Return the steak to the skillet and add salt, black pepper, beef broth, and half & half, stirring gently.
Bring the mixture to a boil, then add the frozen cheese tortellini and stir to coat.
Reduce heat to low, cover the skillet, and simmer for 10 minutes until tortellini is cooked and sauce thickens, stirring frequently.
Remove the lid and sprinkle mozzarella and provolone cheeses evenly over the top.
Cover and let the cheese melt for 1-2 minutes.
Remove from heat and stir the melted cheese into the tortellini and sauce before serving.
