Cook the bacon in a skillet or saute pan until crisp. Drain on paper towels. Reserve 1 tablespoon bacon drippings in the pan.
Bring a pot of salted water to a boil. Cook the pasta until al dente per package directions. Drain.
Place the Alfredo sauce in a small saucepan. Add the garlic, sun-dried tomatoes and crushed red pepper flakes. Bring to a simmer. Add all but a few pieces of the bacon to the sauce, reserving the remainder for garnish.
Place cooked pasta in the sauce and toss to coat; keep warm.
Season sea scallops with salt and black pepper. Heat reserved bacon drippings back up over medium-high heat. Place scallops in the pan and sear 2-3 minutes on the first side and 1 minute on the other side. Remove from heat.
To serve: Place equal servings of the pasta in bowls. Top with 4 scallops each. Garnish with reserved bacon pieces, freshly grated Parmesan cheese and chopped fresh parsley.
