Remove the bottom stems from the chard leaves and wash the leaves well.
Place the washed leaves into a medium size pot.
Add 2 tablespoons of fresh lemon juice and enough water to cover the leaves. (approximately 6 cups of water)
Bring the mixture to a boil, then lower the flame and simmer for 3 minutes.
Drain the leaves into a sieve, then place them into ice water. Let cool and drain the leaves well.
Grate the leaves in a food processor on a large grater disk. You can also opt to finely chop the leaves manually.

Refrigerate for half an hour or freeze for 15 minutes to help solidify the mixture.
Line the baking pan with a baking sheet.
Spread 2 tablespoons of olive oil on the baking sheet within the baking pan.
