In a medium bowl, add chicken broth, milk, heavy cream and flour. Whisk and set aside.
Preheat large skillet on medium heat and swirl 1 tablespoon of olive oil to coat. Add chicken, sprinkle with 1/2 teaspoon salt and 1/4 teaspoon pepper and cook for 10 minutes or until seared and cooked through, stirring a few times but not too often.
Add asparagus, garlic, remaining 1 tablespoon of oil, 1/4 teaspoon salt, 1/4 teaspoon pepper and cook for just 1 minute.
Give sauce a whisk, pour over chicken and asparagus and bring to a simmer. Cook for 1-2 minutes or until sauce has thickened, stirring a few times. Turn off heat and add lemon juice while stirring chicken and asparagus.
Let stand for 3-4 minutes, garnish with chives and serve with your choice of pasta or grain.
