In a medium saucepan on medium heat, add olive oil and sauté lobster shells until bright red on both sides, about 2 minutes.
Add pinot grigio and deglaze for about 2 minutes, then reduce by about half in volume.
Remove lobster shells from pan, add 2 tablespoons unsalted butter, shallots, and garlic; sauté until fragrant and tender, about 2 minutes.
Add minced Calabrian chili and sofrito and sauté for about 40 seconds.
Add remaining 1 lb. unsalted butter and melt; once butter is melted, poach lobster meat for 1 minute.
Remove lobster meat and coarsely chop. Place lobster meat, lemon juice and zest, 1/2 teaspoon kosher salt, 1/4 teaspoon black pepper, and chopped parsley back into saucepan.
Cook about another 2 minutes and season to taste with salt and pepper; serve warm with tomahawk ribeye.
**If you have leftover lobster butter, cool down to room temperature, wrap, and place in refrigerator; re-heat remaining lobster by bringing to medium heat until hot throughout. Use lobster butter within 2 days.
