This is a great recipe from Kerrie.
Thinly slice 4-6 large onions.
Put sliced onions in a large pot with 1 tbs of olive oil and stir around then cook on high for 15 minutes or so until onions are very brown. Toss them around from time to time to make sure they cook evenly.
Chop 1 medium bunch of spinach or argula.
After 15 minutes, check onions…if they are nicely browned, lower heat to medium, add chopped up spinach and 1/2 cup white cooking wine. Let simmer together for 15 minutes more.
While it is simmering, cook pasta.
After it has simmered, add 1 cup feta cheese or a blue cheese. Stir around until melted.
Drain pasta. Add sauce and mix well.
