1. Begin by gathering all your ingredients for the smoothie base. Ensure that your avocados are ripe and ready to use. Ripe avocados should give slightly when pressed gently.
2. Slice the avocados in half, remove the pits, and scoop the flesh into a blender using a spoon. Discard the pits and skins.
3. Juice the lemons until you have 1/2 cup of fresh lemon juice and zest one lemon. Set these aside.

1. In the blender with the avocado, add the 2 cups of unsweetened almond milk. This will serve as the base of your smoothie.
2. Add the fresh lemon juice and lemon zest to the blender. This will give your smoothie a refreshing citrus flavor.
3. Add the fresh basil leaves. These will provide an aromatic and slightly sweet flavor to the smoothie.
4. Pour in the extra-virgin olive oil. This addition will add richness and healthy fats to your drink.
5. Season with sea salt, ground black pepper, and garlic powder to enhance the flavors.
6. Add your chosen keto-friendly sweetener, starting with 1/2 tsp of stevia, and adjust according to your taste preference.

1. Blend all the ingredients at medium-high speed until the mixture is completely smooth and creamy. This should take about 1-2 minutes.
2. Taste the smoothie and adjust seasoning or sweetness if necessary, blending again briefly if you add anything.
3. Pour the smoothie evenly into four glasses.
4. Garnish each glass with a thin lemon slice on the rim and a small fresh basil sprig for an attractive presentation.
5. Enjoy your refreshing Mediterranean Keto Lemon Basil Smoothie, perfect for a healthy and satisfying drink!
