Everything you want on a slow morning, on one plate, with a second cup of coffee close by.
Heat a splash of olive oil in a large pan and cook the bacon over medium heat until crisp. Set aside on paper towel.
In the same pan, cook the mushrooms 4-5 minutes until golden, then push to one side.
Add the cherry tomatoes cut-side down and cook 2-3 minutes until blistered.
Wilt the spinach in the residual heat for a minute, season everything, and set aside.
Wipe the pan, melt a little butter and fry the eggs to your liking.
Toast the sourdough and butter it while warm.
Arrange everything on two plates and serve immediately with the toast.
