Cut chicken tenders into cubes with chef's knife or kitchen scissors. Season with salt and pepper.
Heat large skillet to medium high heat. Add olive oil (1 tbsp) and butter (1 tbsp). When butter is melted, add chicken to hot skillet. Let cook 2-3 minutes per side.
Reduce heat to medium. Then, add garlic (2 tsp), all roasted red peppers (minus the liquid in the jar), orzo (1 cup), Italian seasoning (2 tsp), smoked paprika (2 tsp), kosher salt (1/2 tsp) and black pepper (1 tsp) to the pan. Combine, then cook 2-3 minutes, stirring occasionally.
Add chicken stock (2.5 cups) to the pan and bring to a boil. Then, reduce heat to low (liquid in the pan should be simmering). Cover and cook for 14-15 minutes or until orzo is cooked through.
Add spinach and heavy cream to the pan. Once spinach is wilted, turn off the heat and add the grated parmesan. Stir in parmesan to melt and serve.
