Prepare the Salmon:
Season the salmon steaks with salt, pepper, and paprika on both sides.

Cook the Potatoes:
Heat 1 tablespoon of olive oil in a large skillet over medium heat.
Add the cubed potatoes and cook until they start to brown and become tender, about 8-10 minutes, stirring occasionally. Remove the potatoes from the skillet and set aside.

Cook the Onions and Tomatoes:
In the same skillet, add the remaining tablespoon of olive oil.
Add the sliced onions and sauté until they become translucent, about 3-4 minutes.
Add the minced garlic and diced tomatoes, and cook for another 2-3 minutes until the tomatoes start to soften.

Combine and Simmer:
Push the onion and tomato mixture to the sides of the skillet and place the seasoned salmon steaks in the center.
Pour the chicken or vegetable broth over the salmon and vegetables.
Sprinkle the dried thyme (or add fresh thyme sprigs) over everything.
Cover the skillet with a lid and let it simmer over medium-low heat for 10-12 minutes, or until the salmon is cooked through and flakes easily with a fork.

Serve:
Once the salmon is cooked, gently remove the steaks from the skillet and place them on serving plates.
Spoon the potatoes, onions, and tomatoes around the salmon steaks.
Garnish with freshly chopped parsley.
Enjoy your salmon fish steak with potato, onion, and tomatoes!
