Wash the quinoa and oatmeal. Do not skip this step because we are removing the bitter taste from the quinoa.
Heat the olive oil in a large skillet with a lid and add the quinoa and steel-cut oats. Cook for 2-3 minutes to brown slightly.
Add the broth or water and bring to a boil.
When it is boiling, cover the pot, lower the heat and let it cook for 15 minutes.
After time there should be no water left. Cover again and let stand with the fire off for 15 minutes. These extra minutes finish the cooking and are important for a good result.
While you wait you can prepare the other ingredients, cut the cucumber, onion and fresh herbs.
With a fork mix the quinoa and steel cut oats, empty into a bowl. If you feel it is very hot, let it rest for 5 to 10 minutes since we do not want the herbs to wither.
Add the chickpeas, cucumber, onion, pistachios, feta cheese, mint and parsley.
Season with lemon juice, olive oil, salt and pepper to taste. You can eat right away and let it sit in the fridge so the flavors meld.
