Season the shrimp with all-purpose seasoning.
Sear the shrimp in a skillet with oil until pink and opaque, then set aside.
Deglaze the skillet with dry white grape juice, then melt butter and cook garlic until fragrant.
Add flour, then gradually whisk in stock and cream cheese until smooth. Stir in heavy cream and basil, and simmer.
Cook tortellini according to package instructions, then drain.
Add spinach to the sauce, then mix in red pepper and Parmesan. Combine with tortellini and shrimp before serving.
