Cook eggs in a saucepan of boiling water for 5 minutes, drain, cool in iced water, then peel.
Coarsely tear leaves of greens, steam for 1-2 minutes or until wilted, transfer to a colander to cool, then squeeze to remove excess water.
Heat oil in a saucepan over medium-high heat, add leek and garlic and cook for 5-6 minutes or until very soft. Transfer to a food processor, add greens, process until finely chopped, transfer to a large bowl, add cheeses, vegetables and marjoram, combine and season with sea salt and freshly ground black pepper.
Preheat oven to 180C. Place a 20cm-diameter metal ring on a baking paper-lined oven tray, brush with butter, line with a piece of filo, allowing excess to overhang, brush with butter and top with filo. Repeat with remaining filo and butter, finishing with filo.
Spoon 2/3 of ricotta mixture into ring, smooth surface, then using a spoon create 6 wells around edges. Place eggs in wells, then spoon over remaining ricotta mixture, smoothing top. Fold in overhanging pastry, brushing with butter between each layer, pleating as you go. Brush top with butter and bake for 40 minutes or until golden. Serve warm or at room temperature.
