Wash and cut off ends of your asparagus and coat in olive oil, lemon juice, salt and pepper. Bake on 375 for about 20-25 min or until roasted brown.
For the dressing: whisk dill, garlic, olive oil, mustard, saffron and vinegar in a bowl. Season with salt and pepper. Taste and adjust accordingly depending on taste.
When asparagus is done, drizzle sauce and top with red pepper flakes and cracked pepper. Enjoy!
