Heat a skillet with the olive oil over medium heat.
Add the onions, peppers and garlic and lightly sauté, covered, stirring every now and then until softened.
Uncover and add the meat to the pan along with your zucchini noodles and turn the heat to high.
Stir everything to warm the meat and cook the zucchini noodles (about 1-2min). Add salt and pepper to taste.
Next turn down the heat and place your provolone slices on top and cover until melted. (I actually just broke mine up and stirred them in but you can put them on top to make it more visually appealing when serving! lol).
Serve warm or keep in a sealed plastic tupperware container in the fridge for later!
