Preheat the oven to 300F/150C and place a large frying pan over a high heat.
Leave the pan for 5 minutes to heat up and then cook the tortilla in the dry pan for 3-4 minutes on each side until brown and crisp. When cooked, place the tortilla inside the oven to keep warm.
Drizzle the olive oil in the frying pan and stir in the chopped peppers and onion. Cook for 5 minutes until softened.
Add in the bacon rashers and cook to your liking.
In a small bowl, beat together the eggs and milk. Pour into the frying pan and stir, stir, stir. Cook for about 2 minutes until you've got scrambled eggs.
Remove the tortilla from the oven and spread the veggie and scrambled egg mixture on top. Sprinkle on the grated cheese and place the tortilla back in the oven for about 5 minutes, to let the cheese melt. Alternatively, attack the cheese with a kitchen blow torch to melt.
Sprinkle on the fresh chives then serve.
