Equipment I Used
How to Make It
Prepare the Cauliflower
Chop 1 head of cauliflower into small florets. Steam or boil the cauliflower in a large pot for about 10 minutes, or until tender. The cooking time may vary depending on the size of the pieces.
Sauté the Vegetables
While the cauliflower is cooking, heat 1 tbsp of butter in a large skillet over medium-high heat. Add 1 small diced onion, 3 diced carrots, 2 diced celery stalks, and 2 minced garlic cloves. Sauté the vegetables for about 5 minutes, stirring frequently, until they begin to soften.

Cook the Ground Beef
Push the vegetables to the sides of the skillet, creating a space in the center. Add 1 lb of lean ground beef to the middle, breaking it up with a spatula, cook until no longer pink, about 5-7 minutes. Mix the vegetables and beef together.
Stir in 1 tsp of salt, ¼ tsp of pepper, and 2 tsp of oregano. Mix everything together until the beef and vegetables are well seasoned and blended. Remove the skillet from heat.

Transfer to Baking Dish
Pour the beef and vegetable mixture into an 8×8 baking dish, spreading it out evenly. Do not drain the fat, as it adds flavor to the dish

Mash the Cauliflower
In a bowl, mash the cooked cauliflower with 2 tbsp of butter, and season with salt and pepper to taste. Mash until smooth and creamy.
Spread the mashed cauliflower evenly over the beef and vegetable mixture in the baking dish, smoothing the top.

Bake
Preheat your oven to 400°F (200°C). Place the dish in the oven and bake for 20 minutes, or until the top is lightly golden and the filling is bubbling around the edges.
Remove from the oven and allow the bake to cool for a few minutes before serving.
