Bring large pot of salted water to boil. Cook egg noodles according to package directions until al dente. In the last 2 minutes of cooking, stir in frozen vegetables. Drain, rinse with cold water and set aside.
Replace hot pot back to medium heat. Melt butter, then whisk in flour. Cook 1 minute. Slowly whisk in chicken stock and wine. Sauce should form and start to thicken. Simmer for 3 minutes to cook out alcohol in the wine. Continue whisking to avoid getting lumps. Stir in milk, cream, poultry seasoning, salt and pepper. Cook on medium low heat for another 3 minutes. Stir in cooked noodles and veggies. Add in tuna and parmesan cheese and stir. Top with crushed chips, parsley flakes and serve.
