Yogurt-Spinach Dip with Walnuts

My mom and I made this dip on a recent trip back to Ohio.  It's super flavorful and delicious, plus pretty healthy too!  The recipe makes a ton, so this is a great choice for a crowd.  Make sure to have lots of pita chips for dipping.

Makes dip for a crowd

Heat a drizzle of olive oil over medium heat in a large skillet.  Add 1 cup chopped walnuts and a small diced onion and saute until the onion is softened.  Add a good amount of minced garlic and saute until fragrant.  Set aside to cool slightly.  In a medium bowl, stir together 2 cups whole milk plain Green yogurt, a few handfuls chopped fresh spinach, a bunch of chopped fresh mint, and the juice of one lemon.  Season generously with salt and pepper. Stir in the walnut-onion mixture.  Taste and adjust seasoning.  Serve with pita chips or fresh veggies for dipping.
