Season the chicken breasts with garlic powder, smoked paprika, oregano, salt, and pepper. Heat a grill pan or skillet over medium-high heat and cook the chicken for about 5 to 6 minutes per side. Let the chicken rest before slicing it into bite-sized pieces.
Bring a large pot of salted water to a boil and cook the pasta until al dente according to package instructions. Avoid overcooking because soft pasta can become mushy in the salad. Drain the pasta and let it cool slightly before mixing.
Place the pine nuts in a dry skillet over low heat. Stir frequently until they become golden brown and fragrant. Keep a close eye on them because pine nuts can burn very quickly if left unattended.
In a small bowl, whisk together lemon juice, champagne vinegar, Dijon mustard, honey, lemon zest, minced garlic, salt, and pepper. Slowly drizzle in the olive oil while whisking continuously until the dressing becomes smooth and creamy. Taste and adjust seasoning if needed.
Add the cooked pasta to a large mixing bowl along with sliced chicken, chopped artichokes, parmesan cheese, basil, parsley, and toasted pine nuts. Pour half the vinaigrette over the mixture and toss everything gently to combine evenly.
Cover the bowl and refrigerate the salad for at least 30 minutes before serving. Chilling helps the pasta absorb the lemon dressing and blend the flavors together beautifully. Toss again before serving and add extra dressing if needed.
