2) Brown the chorizo in a frying pan over a medium-high heat, about 8 to 10 minutes. Drain and place into a large mixing bowl.
3) Add the gouda, red onion, egg, cream cheese, sour cream, hot sauce and salt and pepper, to taste.
4) Press the gouda-chorizo mixture into the jalapeno halves and assemble on a greaseproof paper lined baking sheet. Bake until golden and bubbly, about 20 minutes.
