Preheat oven to 350F and lay out phyllo cups on a baking tray.
In a large bowl, whisk together eggs, half and half, and parmesan cheese. Season with salt and pepper. Transfer to measuring cup with a spout and fill cups 3/4 of the way up.
In a smaller bowl, mix the peas, leeks, and bacon together - sprinkle a bit of the mixture into each filled phyllo cup.
Carefully transfer to the oven for 10-15 minutes, until golden brown and baked.
Serve over fresh greens, either warm or room temperature.
