Peanut Butter & Banana Smoothie

3/4 cup (175ml) Lewis Road Creamery Organic Milk
1 medium banana, peeled, cut into 1/2-inch slices, and frozen (about 155g)
2 tablespoons natural peanut butter (about 32g), see notes
1/4 teaspoon salt; for table salt, use half as much by volume


Note: You can use any nut butter you'd like, however we find peanut butter works best. Both creamy and crunchy nut butters will work here. Almond butter, cashew butter, and tahini can be substituted for peanut butter.
