Check out the full recipes below.

Spiced Lamb Nachos with a Cheese Fountain

For lamb:

2 tablespoons oil

1 medium onion, 3 cloves garlic, minced

1 lb. ground grass-fed lamb from New Zealand

1 teaspoon ground cumin

1 teaspoon sweet paprika

1 teaspoon kosher salt

1/4 tsp. freshly ground black pepper

1 tablespoon fresh rosemary, finely chopped

For Yogurt:

1/2 C. Greek yogurt

1 teaspoon dried mint or parsley

1/2 teaspoon kosher salt

For cheese sauce:

4 tablespoons butter

4 tablespoons flour

2 C. whole milk

3 C. grated Gruyere cheese

1 tablespoon fresh rosemary, finely chopped

Toppings:

3 scallions, whites and greens chopped

1/2 C. pomegranate seeds

Tortilla chips

Directions:

Add olive oil to a large sauté pan and heat on medium-high heat. Cook onions until soft, about 3-4 minutes, then add minced garlic and cook 2 more minutes.

Bring heat to high and add ground lamb. As it cooks, break it up into smaller pieces with a wooden spatula. Add cumin, paprika, salt and pepper and cook until the lamb is not pink anymore. Turn off heat and mix in chopped rosemary. Set aside.

Make yogurt sauce by mixing all of the ingredients in a small bowl. Add water, one tablespoon at a time until the yogurt easily drizzles off a spoon. Set aside.

For the cheese sauce, melt the butter in a medium saucepan on medium heat. Once melted, vigorously whisk in flour and continue whisking until it begins to brown. Slowly whisk in milk and allow to thicken, about 3-4 minutes. Remove from heat and whisk in Gruyere cheese. Once smooth, add in chopped rosemary. You may whisk in more milk to thin out if it begins to solidify.

Assemble nachos by placing a double layer of tortilla chips in a skillet or large shallow serving bowl and drizzle with half of the cheese sauce, lamb and yogurt. Cover with another layer of tortilla chips and drizzle the remaining cheese, lamb and yogurt, then top with green onions and pomegranate seeds. Serve immediately.

Note: If you cannot find pomegranate seeds in season, you may substitute them with drizzled pomegranate molasses.
