# How-To Steps:
01 - Set oven temperature to 400°F (200°C) and allow to preheat while preparing the other components.
02 - Bring a large pot of salted water to a boil. Add potato chunks and cook until fork-tender, approximately 15-20 minutes.
03 - In a large skillet over medium heat, warm the olive oil. Add chopped onion, diced carrots, and celery; sauté for 6-8 minutes until vegetables have softened.
04 - Add minced garlic and cook for 1 minute. Incorporate ground lamb, breaking up the meat as it cooks. Sauté until lamb is browned, about 8 minutes. Drain excess fat before proceeding.
05 - Stir in tomato paste thoroughly. Pour in stock, Worcestershire sauce, thyme, and rosemary. Allow mixture to simmer for 10 minutes until slightly thickened.
06 - Stir in frozen peas. Season with salt and black pepper. Remove skillet from heat and set aside.
07 - Drain cooked potatoes and return to pot. Add milk and butter, then mash until smooth and creamy. Mix in half of the grated cheddar cheese. Season with salt and pepper to taste.
08 - Transfer lamb and vegetable filling to a deep baking dish (2-quart capacity). Evenly spread mashed potatoes over filling. Sprinkle remaining grated cheese on top.
09 - Bake in preheated oven for 25-30 minutes, or until the potato topping is golden and the filling is bubbling.
10 - Remove from oven and let rest for 10 minutes before portioning and serving.
