Prepare an ice bath. Place a clean kitchen towel on a flat surface. Bring a pot of water to a boil and add a generous amount of salt.
Using the stem as a "handle," dunk 5-6 leaves at a time into the boiling water. Cook for 15-30 seconds then transfer to the ice bath. Repeat with remaining leaves.
Drain the chard and spread out on the clean kitchen towel. Blot dry with another clean kitchen towel or paper towels.
Cut the stem out of each leaf, making a V-shape and creating two "flaps."
Finely chop the stems.
Heat the olive oil over medium-high heat in a medium saucepan. Add the onion and the chopped chard stems, reduce heat to medium-low. Cook for 6-8 minutes or until beginning to soften.
Add the garlic and cook very briefly approximately 10-15 seconds. Add the vegetable broth, lemon juice, quinoa and raisins. Bring to a boil.
Reduce the heat to low and let simmer uncovered for approximately 15 minutes or until much of the liquid has been absorbed and the germ is beginning to show. Cover and let stand off the heat for 15 minutes.
Stir in the parsley, dill, cayenne, pinenuts and salt and black pepper, to taste. Let cool.
Place equal amounts of the quinoa filling in the center of each chard leaf. Bring the ends up and over the filling, fold in the sides and roll into a neat cylinder shape. Repeat with all the leaves.
Arrange on a serving platter and refrigerate until needed. Serve chilled or at room temperature.
