I like Pacific Natural Foods's organic, unsweetened almond milk in the Original and Vanilla flavors. A cup of Original only has 35 calories. It is not as easy to find in grocery stores as Almond Breeze, but I prefer it. The box has a screw top, rather than the push-up top on Almond Breeze, which has come in handy to prevent spills more than once. One thing to keep in mind is that almond milk does not contain calcium, so if you are substituting it for dairy milk, you will need to get your calcium from another source.
