Boil the potatoes for 10-15 minutes until tender, drain and cool slightly.
Meanwhile, heat 1 tbsp oil in a frying pan and fry the onion for 4 minutes, add the mushrooms and fry for another 3 minutes. Add the spinach and tomatoes and cook for a further 1 minute. Roughly mash the potato and mix into the onion mixture. Season.
Meanwhile, cook the bacon under a preheated grill for 4-5 minutes.
Divide the potato hash into 4 rounds. Heat the remaining oil in a large frying pan and fry the hash rounds for 2 minutes on each side.
