1-2tbspMarmite(Entirely dependent on how Marmitey you want it)
1vegetable stock pot
low calorie cooking spray
Put water onto boil for the pasta. Chop the leek into rings and onions into half moons, both finely chopped.
Fry the leeks and onions in low calorie cooking spray until soft and golden.
Once the pasta is cooked, drain the water, leaving a little bit in the pan - not too much otherwise it will be too watery. Add the vegetable stock pot, Marmite and fried vegetables and mix until combined.
That's it! Really simple, quick and adaptable. Enjoy!
