For the breadcrumbs, heat a skillet over medium-high heat with the butter, panko, and salt. Stir to combine until the breadcrumbs are lightly golden, then turn the heat off the skillet. Add the garlic and parsley and stir a few more times, then set aside until ready to use.
For the tuna noodles, cook the pasta to al dente and reserve a cup or so of the cooking water right before draining. Then, preheat a large ovenproof skillet to medium-high heat and the oven to 350F.
When the skillet is hot, add the butter and the flour. Stir to form a paste, then slowly pour in the wine, whisking as you go. Pour in the milk in the same way, very slowly, whisking as you go so the milk incorporates with the flour/wine mixture. Add the seafood seasoning and the hot sauce. When the sauce is bubbly and thick, gently stir in the noodles, tuna, cheese, and peas. Taste the sauce and add salt and pepper to your preference, then turn off the heat and sprinkle the garlic breadcrumbs over the entire skillet.
Bake the dish at 350F for 10 minutes, then broil for 1-2 minutes to brown the top of the dish.
Enjoy!
