Prepare the spinach: Heat 1 tablespoon of the olive oil in a large saute pan. Add onions and cook till translucent, 4-5 minutes. (I used season blend, which is a bag of chopped onions, red bell peppers & celery already chopped.) Add garlic and cook till fragrant, 1 minute more. Add the spinach in batches, allowing it to cook down before adding more. Cook until all spinach is wilted, 5-6 minutes. (I only used about 3 cups of spinach)
