Step 1: Cook the Pasta

1. Fill a large pot with salted water and bring it to a boil.
2. Add the fettuccine pasta and cook according to package instructions until al dente. This usually takes about 8-10 minutes.
3. Drain the pasta, toss with a drizzle of olive oil to prevent sticking, and set aside.

Step 2: Prepare the Chicken Bites

1. Season the chicken cubes with salt, pepper, and Italian seasoning. Toss well to coat.
2. In a large skillet, heat 2 tablespoons of olive oil over medium-high heat.
3. Add the chicken bites to the skillet in a single layer, cooking until golden brown on all sides (about 6-8 minutes). Ensure they’re fully cooked, then remove them from the skillet and set aside.

Step 3: Make the Creamy Tuscan Sauce

1. In the same skillet, add 1 tablespoon of olive oil and 2 tablespoons of butter. Allow the butter to melt and bubble.
2. Add the minced garlic and sauté until fragrant (about 1 minute).
3. Stir in the chopped sun-dried tomatoes and cook for 2-3 minutes.
4. Pour in the chicken broth and let it simmer for 2 minutes, scraping any brown bits from the bottom of the pan.
5. Reduce the heat to medium-low and add the heavy cream. Stir continuously until the sauce begins to thicken (about 3-4 minutes).
6. Add the grated Parmesan cheese, Italian seasoning, and crushed red pepper flakes (if using). Stir until the cheese melts and the sauce is smooth.
7. Return the cooked chicken bites to the skillet, stirring well to coat them in the creamy sauce. Let the mixture simmer for another 2-3 minutes. Taste and adjust salt and pepper if needed.

Step 4: Prepare Spinach & Tomato Mix

1. In a separate large skillet, heat 2 tablespoons of olive oil over medium heat.
2. Add fresh spinach and cherry tomatoes. Sauté until the spinach is wilted and the tomatoes are softened (about 3-4 minutes).
3. Season with a pinch of salt. Remove from heat and set aside.

Step 5: Combine & Serve

1. Toss the cooked fettuccine with the sautéed spinach and tomato mixture.
2. Plate the fettuccine and top generously with the creamy Tuscan chicken bites.
3. Garnish with additional freshly grated Parmesan and chopped basil or parsley.
4. Serve hot and enjoy!
