Simply Yummy Asparagus!! Preheat oven to 400 degrees F. Toss or mist the asparagus with olive oil and 1 Tbsp. lemon juice until evenly coated. Sprinkle with a pinch or two of sea salt, and then generously season with freshly-cracked black pepper. Roast for 8-12 minutes, or until the tips begin to brown and the asparagus is tender. Remove and garnish with lemon zest.
