4 tablespoons butterdivided

freshly cracked pepper to taste
Instructions
Heat a large dutch oven or heavy-bottomed pot over high heat. When the pot is hot, add 1 tablespoon olive oil and the ground turkey. Season generously with salt and pepper and cook, breaking up the meat with a flat wooden spoon, until very well browned, about 5-7 minutes. Remove the meat from the pot and place in a bowl. If using ground beef or lamb, make sure to drain any excess oil.
In the same pot, heat the remaining 2 tablespoons olive oil over medium heat. Add onion (and any other diced fresh, but not frozen, vegetables you are using) and cook until softened about 5 minutes. Stir in the garlic and cook 30 more seconds.
Add the tomato paste and thyme sprigs and cook, stirring often, until the tomato paste starts to slightly caramelize about 2-3 minutes. Be careful not to let it brown or burn.
Place the turkey back in the pot and add the chicken stock, worcestershire sauce, and red wine, if using. Bring the mixture up to a boil then reduce the heat and simmer gently for 20-25 minutes, stirring occasionally.
Preheat the oven to 400°F.
While the meat mixture simmers, place the potatoes pieces in a medium saucepan and cover with cold water by at least 2 inches. Add a very generous pinch of salt and bring to a boil. Once it reaches a boil, reduce to a steady simmer and cook for 12-15 minutes or until the potatoes are very tender but not falling apart.
In a small saucepan, heat the milk and 3 tablespoons of butter until the butter is melted. Alternatively, heat the milk and butter in the microwave.
Drain the water from the potatoes completely and place the saucepan with the potatoes over a low heat burner for 1 minute to cook off any residual water. Turn off the heat and mash the mixture very well with a potato masher or ricer. Pour in the warm milk and melted butter and season to taste with salt and pepper.
Taste the meat mixture and adjust seasoning if necessary by adding more salt and pepper or worcestercshire sauce. Pour the turkey mixture into a 9x9 (or 7x11 or 2-3 quart) baking dish and spread it out into an even layer. Place the frozen peas and corn in an even layer over the meat mixture.
Spoon the mashed potatoes on top carefully spreading it into an even layer. Once the top surface has been covered, use a spoon or fork to create texture so that there are peaks that will brown nicely. Dollop small pieces of the remaining 1 tablespoon of butter over the potatoes.
Bake uncovered for 25-30 minutes, or until the filling is bubbling. If the topping needs more browning, turn on the broiler and cook for 3-5 minutes, watching it carefully so it doesn't burn. Cool for 15 minutes before serving.
Notes
*If omitting the wine, add an extra 1/2 cup chicken broth to the meat mixture.
