Place chicken breasts in a large zip-loc bag and season with olive oil, thyme, rosemary, oregano, garlic, salt and pepper. Refrigerate for 1 hour and up to 1 day
Preheat grill to medium-high heat and grill the chicken breasts 8-12 mins (4-6 mins per side) or until done; remove from grill and let cool. 3. Bring a large pot of salted water to a boil. Blanch asparagus for approximately 2-3 mins. Using tongs, remove the asparagus and immediately shock in an ice bath; set aside.
Using the same pot of water, boil pasta until al dente, about 8-10 mins; drain pasta.
While pasta is cooking, heat a sauté pan to medium-high heat with a light drizzle of olive oil. Sauté the artichokes, asparagus, peas, and sun-dried tomatoes until heated thoroughly. Remove from heat and toss in the fresh spinach and pasta.
Meanwhile, in a small saucepan, gently heat Alfredo sauce until warm.
Slice chicken breast thinly into strips. Add the sliced chicken to the vegetable and pasta mixture. Toss the pasta mixture with Alfredo sauce and serve immediately. Enjoy with a light sprinkle of fresh Parmesan cheese and a refreshing glass of Pinot Grigio.
