Do you like crustless quiche and have time to make an oven tray sized one at the weekend?
Mixing together 9 large eggs, 750g of quark and a couple of bags (360g) of Eatlean protein cheese will give 5 portions (one for each workday morning) for a total of 362 calories and containing 58 g of protein before you start adding your favourite vegetables.
The addition oil and vegetables do increase the calorie content, but they vary so wildly that I haven't tried to add them to the nutritional value. Don't skimp on a wide variety of vegetables, especially when you are restricting calories.
Mushrooms, spinach, broccoli, peppers and asparagus all contain different micronutrients and fibre, but adding a tin of cooked beans (air fried or roasted with the other vegetables) will boost the fibre content if you are having trouble meeting your daily target.
I try to eat to improve my gut microbiome so I start preparing the quiche by air frying a load of chopped vegetables, seasoned and brushed with olive oil. Then use the same brush to oil the oven pan. The cooked veg go into the oven tray, the seasoned egg, quark and cheese ( the gut bug overlords prefer loads of herbs, different coloured ground peppers, garlic granules, grated nutmeg, paprika, chilli pepper, whatever I fancy from the spice rack - though not all in the same quiche!) goes over the vegetables and the top gets decorated with sliced tomatoes, peppers and a bit more cheese. Bake for 45 minutes at between 160 and 175, and leave it to stand for 20 minutes so that the middle sets. Though I usually end up putting it back in the oven for a bit longer because I'm not keen on barely cooked wobbly eggs.
My crustless quiche has no pastry at all. So perhaps it's an oven omelette or something else entirely? Anyhow it is easy to make, the vegetables, herbs, seasonings and cheeses can be changed according to what needs using up or what you fancy eating, and it is good cold if you are in a rush, or you can warm it in the micro while you brew your breakfast coffee.
