Pan Seared lemon butter salmon

This is a really good recipe made up of different recipes I found online. It's not too fattening either! Butter can be substituted for olive oil.
You will need:
1 filet of salmon cut in 2-4 pieces
1 1/2 Tbsp butter
1/2 lemon
1/4 tsp minced garlic
dried or fresh Rosemary
salt to taste (I prefer seasoning salt)
pepper to taste
1 package of baby spinach (rinsed)
1 tsp butter

1. 
   
   Cut and season the fish with ingredients 5-7
2. 
   
   Melt 1 tbsp of butter on med high heat with the garlic
3. 
   
   squeeze the lemon in the butter
4. 
   
   Add fish skin side down for about 5 mins; flip and do the same for the other side until golden brown (if butter dries up add remaining 1/2tbs butter).
5. 
   
   Remove fish from pan, put aside
6. 
   
   Squeeze remaining lemon juice on fish (optional)
7. 
   
   Without cleaning out pan add the 1 tsp butter
8. 
   
   Add spinach
9. 
   
   Cook until wilted
10. 
    
    place fish on top of spinach and serve
