I bought some rhubarb (lower potassium vegetable) at a farmer's market but wasn't sure how I was going to use it. Usually you have to add a lot of sugar to make it palatable. Perusing my old Betty Crocker cookbook, I found a strawberry/rhubarb pie that sounded so delicious. I replaced the sugar with zero calorie erythritol & monk fruit from Costco and substituted almond flour for regular flour. I'm not totally sure this fits within CKD guidelines but it was absolutely delicious. I somehow always associate rhubarb with fruits - not so!
