Place a non-stick medium pot on medium-low heat.
Add the olive oil and the onion slices.
Cook for 20-25 minutes, stirring occasionally, until the onion softens and gets a nice colour.
Be patient, because this procedure will add extra deep taste to your fava.
Be careful not to burn the onion!
Add the yellow split peas and stir again.
Cook for additional 5 minutes.
Pour in the water and the cube of bio vegetable or chicken stock, if you are using.
Stir and cover with a lid.
Simmer for approximately 1 hour, stirring occasionally, until the split peas are soft and mushy.
If water evaporates too soon, add some boiling water.
At the end of the cooking procedure, there should be no water left in the pot.
When fava is ready, transfer it in a food processor.
Blend until it becomes creamy and smooth.
Serve fava in a deep plate.
Drizzle some olive oil and fresh lemon juice.
Add some onion slices and capers.
Sprinkle with freshly ground pepper and parsley.
Serve and enjoy!
