To prep the chard, , start by taking the stems and center ribs out and chop them together, placing in a bowl. You can also chop the stems off and leave the center ribs on, the choice is up to you. Tear the, leaves coarsely and set aside in a different bowl.
(You can either cook the stems OR leave them out if you only want the leaves. I like a bit of texture, so I cook them first until tender.)
In a large skillet heat the olive oil.
Place the bowl of stem/rib pieces into the hot oil and saute until the ribs are tender.
Add in the leaves and the garlic and, saute until they have wilted and cooked.
Remove from the heat and stir in the lemon juice and lemon zest.
Sprinkle with the Parmesan, salt and pepper.
Serve hot.
Notes
If you really want a strong garlic flavor, use more garlic in this recipe.
