To make sauce, combine spinach, tomato sauce, 1 tsp. garlic, salt,
pepper, thyme, basil, chili flakes, olive oil and lemon juice, reserving
lemon half. Set aside.
In a large saute pan, heat butter on medium heat. Add shrimp and garlic. Season with salt and pepper.
When shrimp is 3/4 of the way cooked, add sauce, Cajun seasoning, diced tomatoes, scallions, black olives, and banana peppers. Cook 2-3 minutes. Toss with pasta and squeeze remaining lemon over pasta.
