If using, toast the cumin seeds by placing them in a large 12-inch skillet and heating it, shaking or stirring the seeds until they are fragrant and have darkened slightly, about 1 minutes on medium heat.Pour the cumin seeds into a mortar and pestle and then lightly crush them. If you don’t have a mortar and pestle, let the cumin seeds cool, then place them in a freezer Ziploc bag and crush them with a rolling pin.
Trim and remove the Swiss chard stems from the leaves. Cut the stems into ½-inch pieces. Slice the chard leaves into 1-inch ribbons.Place the oil, sliced leeks, garlic cloves and chopped chard stems into the 12-inch skillet used to toast the cumin. Cook on medium heat, stirring frequently, until the leeks have softened, about 3 minutes. Do not let the garlic brown or caramelize.
Add the chard leaves, spinach, oregano leaves, and 2 tablespoons of the chopped parsley, along with the crushed cumin. If all the chard and spinach doesn’t fit, cook it in batches, adding half the greens, and then adding the other half after the first batch has wilted down. Continue to cook until all the greens have wilted down.
Sprinkle the black olives, green olives and feta cheese over the top of the greens, then make a well in 5 different spots in the greens.
Crack an egg into each well. Cover with a lid and let cook on medium low heat for 3 to 5 minutes, or until the eggs are cooked to your liking.Remove and sprinkle with remaining parsley, Aleppo pepper (or red pepper flakes), salt and pepper to taste. Serve with slices of toast and lime wedges if you’d like.
