Bring a pot of salted water to a boil and cook the pasta until al dente, reserving two tablespoons of pasta water before draining.
In a large skillet over medium heat, cook the chopped bacon until crispy, then remove the bacon bits and set aside, leaving the rendered fat in the pan.
Season the cubed chicken and steak with sea salt, black pepper, garlic powder, and smoked paprika.
Increase the skillet heat to medium-high and sear the chicken and steak in the bacon fat until golden brown and cooked through, then remove and set aside.
Add the sliced peppers and red onion to the same skillet, sautéing for three minutes until tender-crisp and slightly caramelized.
In a small bowl, whisk together the egg yolk and heavy cream until smooth.
Reduce the skillet heat to low, return the pasta, meats, and bacon to the pan, and toss with the reserved pasta water.
Remove the pan from the heat and quickly stir in the egg and cream mixture, tossing constantly to create a silky sauce without scrambling the egg.
