Combine flour, salt, pepper, and Italian seasoning in a wide shallow dish and mix well.
Dredge the chicken tenders in the flour mixture, shaking off any extra coating.
Heat 2 tablespoons of oil in a large cast iron or frying pan over medium-high heat.
Cook the chicken tenders for about 2 to 3 minutes on each side until golden brown and fully cooked (165°F internal temperature).
Remove the chicken from the pan and keep warm by covering with foil.
While the chicken cooks, boil a large pot of salted water and prepare the angel hair pasta until al dente per package instructions.
Reserve one cup of the pasta water, then drain and set the pasta aside.
Wipe the skillet clean, add 1 tablespoon of oil, and heat over medium heat.
Add the sliced red, yellow, and green bell peppers along with the red onion, sautéing them for 3 to 4 minutes while stirring frequently.
Mix in the butter and minced garlic, cooking everything for another 1 to 2 minutes until the vegetables soften.
Pour the white wine into the pan, scraping the bottom to loosen any browned bits, then add the chicken broth and cook for 2 more minutes over medium heat.
Stir in the heavy cream, Italian seasoning, and salt, bringing the mixture to a gentle boil while stirring regularly.
Lower the heat and toss the cooked pasta into the sauce, mixing well to coat and cooking for 1 to 2 minutes.
Add reserved pasta water by spoonfuls as needed to reach your desired sauce consistency.
Place the cooked chicken on top of the pasta and sauce.
Sprinkle grated Parmesan cheese, chopped fresh basil, and parsley over the dish.
