1/2CupFrozen Petite Peas
Make The Potatoes:
Peel the potatoes and slice them into 1/2 inch chunks. Add them to a medium saucepan filled with cold water. Cook on high, covered, and bring to a boil. When they boil, remove the lid, and lower heat and simmer until potatoes are tender about 10-15 minutes.
Add half-and-half and butter to a small microwave-safe dish and heat the mixture up in the microwave until warmed, approximately 40 seconds.
Drain the potatoes well then place them back in the saucepan. Mash the potatoes until there are no lumps, then stir in the heated half-and-half mixture, salt, and pepper. Add the egg yolk and stir until it's completely absorbed.
Make The Filling:
Meanwhile, as the potatoes cook, begin the filling. Preheat the oven to 4oo degrees.
In a 12 inch skillet, heat the vegetable oil until it begins to simmer over medium-high heat. Add the onions, and carrots and cook until they just begin to brown a bit, about 3-4 minutes. Stir in the garlic. Stir in the lamb or beef, salt, and pepper and saute until the meat is cooked through and no longer has any pink. Drain excess fat (**See Recipe Notes ) Sprinkle the meat mixture with the flour and stir to evenly coat. Cook for 1 minute. Stir in the tomato paste, chicken broth, Worcestershire, rosemary, and thyme. Bring the mixture to a boil, then reduce the heat and cover, and gently simmer, until the mixture thickens a bit, about 10-12 minutes. Stir in the thawed and well-drained corn and peas.
Pour filling mixture into an 11 X 7-inch baking dish. Spread the top evenly with the mashed potatoes, taking care to create a "seal" to the edges of the baking dish. Place baking dish on an aluminum foil-lined, rimmed baking sheet. Bake in the middle of the preheated oven until the potatoes begin to brown, and the filling is heated through in the center, about 25-30 minutes. Allow the casserole to cool on a baking rack for 15 minutes before serving.
