Quinoa can be boiled in large quantities, and then added to the roasting to taste before serving, can be combined with other vegetables.
In this case, add quinoa to the casserole, season with vegetable oil (I like olive oil), lemon juice or cut the peeled lemon into small pieces and mix. In this form, you can already serve as a side dish!
For the salad version, cool the porridge a little, cut the cucumber into cubes (you can add more to taste, I had a large one, one was enough), mix the cooked quinoa with cucumber and olives. Done!
