In a 12 inch cast iron Dutch oven, bring chicken broth to boil over high heat using a campfire, camp stove or RV stove for cooking.
Add the pasta and cook covered till al dente and still firm to the bite, about 5-10 minutes. Do not drain any liquid from the pot.
Reduce the heat to medium-high and stir in the chicken, tomatoes, cream cheese, Cajun seasoning, jalapeno, salt and pepper.
Cook covered till the chicken is heated through and cream cheese is melted, stirring occasionally. Remove cover and continue cooking until the sauce reaches your desired thickness, about 5-10 minutes total.
Top with fresh parsley, if desired, and serve hot.
