1. Cut the crusts off your bread and use a mug to press a hole in the center. Yes, we're about to make "egg in bread".

2. Put your baked beans on a low heat and stir occasionally.

3. Add a glug of olive oil and a knob of butter to a griddle pan. When hot, gently lay your slice of bread in and let it fry for a minute until golden on the underside.

4. Flip it over, bring the heat down and crack an egg into the hole.

5. Chuck a few mushrooms in the pan and squeeze a bit of lemon on them. Let everything cook through (don't turn the egg-bread, just let it cook from underneath).

6. Garnish with something green - a rosemary sprig or a fried sage leaf would do nicely.

7. Season your egg with a bit of freshly ground salt and pepper.
