Key Lime Smoothie

Don't be scared by the color it doesn't taste green at all! Key lime is one of my favorite flavors. This smoothie is sooo refreshing! Make sure to blend very well to avoid a gritty consistency from the lime peel. Double the recipe for more servings to share :) 
1 banana
1/8 to a 1/2 avocado
1 med. lime(juiced) + 1 wedge with skin on (or 2 - 3 key limes juiced + 1/2 key lime skin and all)
1/4 C. milk
2 tsp. vanilla extract
1/4 tsp. stevia powder
1/2 C. non-fat greek yogurt
1 tsp. ground flax seed
2 C. (or more if you like) Spinach
1 C. ice

Add ingredients in order listed and blend very well. Add ice and blend to desired consistency. Serve immediately. Makes 1 smoothie
