Kefir Key Lime Smoothie

I don’t usually cook with limes, but I had a few left in the fridge. (I used the lime rinds to make homemade limecello instead of limoncello…which was amazing!) And I’m running low on fresh fruits and vegetables because I’ll venture on my weekly grocery trip tomorrow. So, what could I whip up with limes? I opted for an afternoon smoothie in key lime style.

I squeezed about 2 tablespoons of juice from the limes. It’s so aromatic! Then I needed a creamy base, which is perfect for kefir. Don’t have kefir? Yogurt will work for this recipe as well. I prefer kefir because it has less sugar than yogurt and even more abundant probiotics for your gut. 

I tossed in a handful of spinach because–if I’m honest–I put spinach in every single smoothie I ever make. Plus it will turn this key lime smoothie a lovely hue of light green.

A tablespoon of flax seeds for some fiber, a banana to keep it thick, and a drop of honey to compensate for the bitter lime juice. I added a few ice cubes since none of my ingredients were frozen, but you could omit these.

A quick thirty seconds in my Vitamix was all it took to whip up this kefir key lime smoothie. The result was a frothy, mint green drink that makes my mind wander to distant beaches with the warm sunshine and crystal clear ocean water.
