Season salmon and shrimp with salt and pepper, plus your favorite seafood seasoning and set aside. (I use a combination of chipotle powder, garlic powder and Simply Organic seafood grilling seasoning.)
Cook 4 sliced strips of turkey bacon in a large stock pot or dutch oven over medium heat for 3-4 mins, stirring occasionally. Bacon should still be pliable.
Add oil, potatoes, onion, celery, garlic, carrot (and jalapeno if using) to the same pot with bacon, season with salt and pepper and cook until onion is softened (approx 5-6 mins), stirring often. (Note: If you're using regular bacon, the fat will likely omit the need for oil.)
Add stock (enough to cover potatoes), stir and bring to a boil. Then cover, reduce heat and simmer until potatoes are tender (about 10-12 mins).
Meanwhile, spray a large grill pan or cast iron skillet with cooking spray and cook salmon and shrimp over medium heat (salmon ~4 mins per side, shrimp ~2 mins per side). Remove from heat, cut into chunks and set aside.
Using a potato masher, gently break down some of the potatoes to desired consistency. You will begin to see the liquid thicken up.
Stir in half & half, salmon, shrimp, dill and butter. Simmer for 3-4 minutes, finish with a little more salt and pepper, then serve with bacon crumbles and fresh dill.
