Place a medium skillet over medium heat and add the diced bacon and chorizo.
Cook for 5-6 minutes until the chorizo is browned and the bacon is crisp, then remove the meat with a slotted spoon, leaving the rendered fat in the pan.
Add the diced bell peppers and halved cherry tomatoes to the skillet, sautéing for 4 minutes until the peppers are tender and the tomatoes are slightly blistered.
While the vegetables cook, toast the sourdough bread until golden brown and set aside on a plate.
In a small bowl, whisk the eggs with sea salt and black pepper, then pour them into the skillet with the vegetables, adding the olive oil if the pan is too dry.
Gently stir the eggs over medium-low heat for 2-3 minutes until they form soft, velvety curds.
Fold the cooked chorizo and bacon back into the egg mixture to combine.
Spoon the chorizo and egg mixture generously over the toasted sourdough and serve immediately.
