Preheat your oven to 350°F (175°C).
In a skillet, heat olive oil over medium heat.
Add sliced onions and bell peppers; sauté until softened, about 5-7 minutes.
Stir in minced garlic and smoked paprika; cook for an additional minute.
Season the mixture with salt and pepper; set aside.
In the same skillet, add the chicken breasts; cook until no longer pink, about 6-8 minutes per side.
Once done, shred the cooked chicken using two forks and mix it with the vegetable mixture.
Place the bottom halves of the slider rolls in a baking dish; spoon the chicken mixture on top.
Top with provolone cheese slices, then cover with the top halves of the rolls.
Bake for 15-20 minutes or until the cheese is melted and the rolls are lightly golden.
Remove from the oven and let cool slightly before serving.
Garnish with fresh parsley if desired and serve warm.
