Prickly Pear and Kumquat

I planted a prickly pear cactus and Kumquat.  The Prickly Pear (Opuntia) will provide fruit and nopale pads, which can be eaten raw or cooked.  They are excellent cooked with egg and cheese, perhaps some mushrooms and onion added to the mix.  The Kumquat has edible fruit.  The peel of the fruit is sweet and the pulp of the fruit is sour.  Kumquat is in the genus Fortunella, which is closely related to the Citrus genus.
