We love lemon on our cucumbers, so this wasn't tart or sour for us. I used half the taco seasoning, but it was still plenty. This would make a nice side dish for tacos or a taco like dish.
We have a garden full of cucumbers. This was a pretty neat way to make them. You are right! These suckers are sour! Then there was the small bit of heat from the taco seasoning. I thought these 3 simple ingredients mixed very nice. Thanks!! :)
