This is one of those dishes that looks like you planned and labored over it for hours. Hours, I tell you! Please don't tell anyone that (including making the homemade marinara sauce) it will take you about 30 minutes. Yup, 30 minutes is all that is standing between you and some tender shrimp bathed in marinara sauce and nestled in a warm and wonderful bowl of creamy polenta. (Side note: I have a secret craving to write menu descriptions - can you tell? I would totally order something described as tender shrimp bathed in marinara sauce and nestled in a warm and wonderful bowl of creamy polenta.) But since I don't have a restaurant, the Southern husband is just going to have to fill in as the one who gets to hear my dramatic descriptions. So let's go make it!
