Spray the loaf tins (I use 2) lightly before starting.
Whisk the milk and eggs together with salt, pepper and an additional 100ml water. Pour a scoop full in the bottom of each loaf tin. Then layer the rocket and spinach, 1/2 the bacon, the mushroom and top with grated zucchini and then the remaining bacon. Pour the remaining egg mix over the top and finely grate some romano cheese on each. Top with the asparagus at the end.
Pop into a moderate oven for about 30 or so minutes, you'll notice when it's golden on top and a skewer comes out clean. Very tasty and low in calories for those days where you've splurged.
