  • 1 1/2 cups quinoa, uncooked
  • 2 1/2 cups water
  • 1 large onion, thinly sliced
  • 4 large garlic cloves, minced
  • 1 tbsp avocado oil
  • 2 cups any milk (I used unsweetened almond milk)
  • 1 tbsp cornstarch
  • 2 cups artichoke hearts, coarsely chopped*
  • 11 oz package (4 large handfuls) spinach
