This is a simple and delicious supper for your family any night of the week!
Cook bacon in a large skillet over medium heat until crisp. Add onion and poblano and cook until softened, about 5 minutes. Stir in garlic and butter and cook until butter has melted. Remove from heat. Add breadcrumbs, 3 tablespoons parsley, and 1/4 cup water; stir to combine. Season with salt and pepper; transfer to a bowl to cool.
Using a spoon, stuff each calamari body with about 2 tablespoons breadcrumb mixture; thread a toothpick through the open end to enclose. Sprinkle stuffed calamari with any remaining breadcrumb mixture.
Heat oil in a large skillet over medium-high heat. Add calamari and cook until golden, 2 to 3 minutes. Turn and continue to cook 2 more minutes. Add wine; let reduce for 30 seconds. Add tomatoes and cook, until sauce thickens slightly, about 5 minutes. Sprinkle with remaining tablespoon parsley. Remove toothpicks and serve immediately with creamy polenta.
