A slight, luxurious advance on that:
1. Fry some bacon (cut into bitesized chunks) until it's almost done, then add mushrooms.
2. Let cook for a while.
3. Do some pasta in the meantime.
4. When the mushrooms are done drain the bacon fat and store for another day, then add some pesto, basic and some water from cooking the pasta.
