Step 1

Heat the oven to 200C / 400F.

Step 2

First, prepare the mushrooms and onions for roasting.Arrange the whole mushrooms and sliced onion in a wide shallow casserole dish. Try to keep the onions in their half-moon shapes rather than breaking up the individual slices, this will slow down their cooking time to align better with the mushrooms.The pan should be pretty much full, but still have the ingredients in one single layer. Drizzle with olive oil and balsamic vinegar. Add salt and pepper to taste.

Step 3

Place in the oven for 20 minutes, or until the mushrooms are browned and reduced and the onions are soft and browning at the edges.

Step 4

Next, we will add the garlic, rosemary and spices.Ensure you have everything measured out and ready to go, then remove the pan from the oven and very quickly mix in the garlic, rosemary, cumin and cinnamon. The residual heat in the pan will soften the garlic and bring out all the fragrances.

Step 5

Add the olives, canned tomatoes and white beans. Add a good amount of salt and pepper to taste. Mix through, cover, and place back in the oven for at 30 more minutes.

Step 6

Add the kale and zest about 1/3rd of the lemon into the pan (about one teaspoon of zest). Give it all a good stir, cover it up again and place back in the oven for 5 more minutes to give the kale a chance to soften up.You can then cut the lemon into wedges for serving.

Step 7

Serve!Scatter with feta (if using) and add lemon wedges for squeezing, then serve with bread or cooked grains.
