Melt butter over medium heat in a large sauce pan or dutch oven. Add sliced onions, water, tomatoes, and salt. Bring to a simmer and cook for 40 minutes, uncovered. Remove from heat, add in heavy cream, and blend until smooth using a hand-held immersion blender.
Garnish with parmesan cheese and chopped green onions. Serve immediately.
