(because at this time of year, you can just name everything starting with "spring"-)
Pineapple makes smoothies wonderfully fluffy. You can add one or two drops of apple cider vinegar as well if you want your smoothie a bit more edgy.
So, here we go:
Cloudy apple juice
The juice of one lime
About a coffe cup of frozen small pineapple chunks
Woom! in the blender and there you have it!
