Pour in the crushed tomatoes and add the dried oregano. Season with salt and pepper. Bring the sauce to a simmer and let it cook for about 10 minutes, stirring occasionally.
While the sauce simmers, season the salmon fillets with salt and pepper.
Carefully place the salmon fillets into the sauce, skin-side down. Cover the skillet and cook for about 8-10 minutes, or until the salmon is cooked through and flakes easily with a fork.
Once the salmon is done, drizzle the lemon juice over the fillets and sprinkle with fresh parsley.
Serve the salmon over cooked pasta, spooning extra sauce on top.
Notes
For a milder version, reduce the amount of red pepper flakes or omit them entirely.
You can also add vegetables like spinach or bell peppers to the sauce for extra nutrition.
For a gluten-free option, serve the salmon over zucchini noodles or cauliflower rice.
