Ingredients for Grilled Asparagus and Spring Onions With Lemon Dressing

  • 1 teaspoon finely grated lemon zest

  • 1 teaspoon finely grated Meyer lemon zest

  • 1 tablespoon fresh lemon juice

  • 1 tablespoon fresh Meyer lemon juice

  • 1 tablespoon whole grain mustard

  • 60ml olive oil, plus more

  • Kosher salt, freshly ground pepper

  • 2 large bunches thick asparagus, trimmed

Prepare grill for medium-high. Whisk lemon zest, Meyer lemon zest, lemon juice, Meyer lemon juice, mustard, and 60ml oil in a medium bowl to combine; season dressing with salt and pepper (if you don’t have Meyer lemons, use regular lemons in their place).
