Mix all the ingredients together to make the batter and start baking them! Make them thin, much thinner and bigger as your average american pancake, but if you're dutch; they are the same as a regular crepe... You need them to be the same thickness.
Heat a large pan with some butter or oil and bake the bell peppers until cooked. Add the mushrooms and cook until done. Now add the chorizo and the ground meat.
Cook until everything is cooked. Drain any excess fat if necessary. Chorizo can sometimes release quite a lot of fat. Better to drain of anything you don't need.
Now season your filling with the chives and salt and pepper. Mix the cream cheese in and spread over your blintzes. Fold it up and serve right away.
