Begin by bringing a large pot of salted water to a rolling boil over high heat.

Once boiling, add your choice of pasta and cook according to the package instructions until al dente, typically around 8-10 minutes.

While the pasta cooks, heat a skillet over medium heat and melt the butter until it bubbles gently.

Stir in minced garlic and flour, cooking for approximately 30 seconds.

Whisk in the apple cider vinegar, Dijon mustard, lemon juice, and Italian seasoning, cooking for about 3-4 minutes.

Reduce heat to low and stir in Parmesan cheese and fresh spinach, allowing the spinach to wilt.

Drain the pasta, reserving a cup of pasta water. Add the pasta to the skillet and toss to coat.

Season with salt and pepper to taste. Serve immediately.
