In a large skillet over medium-high heat, arrange the asparagus spears in a single layer. Cook for 2 minutes until a slight surface char develops.
Add the MagicalButter and garlic, stir, and let simmer for 3-5 minutes, depending on thickness of the spears.
Add the harissa paste, and stir thoroughly. Then, add the lime juice, stir well, and let simmer for about 5 minutes, or until the preferred doneness is achieved. Don’t overcook—no one likes a limp spear!
Garnish your Harissa Butter Asparagus with the cilantro and lemon zest. Serve, and enjoy!
