On a recent grocery run to Kroger I found this So Delicious Green Tea frozen dessert. I liked the fact that it is made with coconut milk and soy free.
A half cup serving is only 130 calories - it is sweetened with organic agave syrup and not overly sweet. It contains green tea powder and I found that the delicious green tea flavor really stands out.
One day I may try making homemade green tea ice cream with Matcha powder, but until then this is a nice alternative.
