In a large nonstick pan, heat butter.
Add salmon, skin up.
Let skin brown, about 3-4 minutes.
Flip and let salmon skin crisp, another 3-4 minutes.
When salmon has browned on each side, remove from pan.
Add garlic to pan, let brown and soften.
Add roasted red peppers and italian spices.
Stir to mix.
Add in stock or wine, and lemon juice, and let come to a boil, stirring often.
Turn heat off, and slowly add in cream, whisking vigorously to combine.
Slowly return heat to medium high and add salmon back to pan, top with spinach and lemon wedges.
Let spinach wilt, and salmon fully cook, ladling sauce over fish to help them cook.
When sauce is thickened and salmon is cooked through, remove from heat and serve - with vegetables, over pasta, or with rice!
