Creamy Zucchini Soup with Lemon and Sour Cream

I love soup. Soup is so easy to make and is full of nutrients. I have a bounty of Squash. I also used the Yellow Crookneck Squash from my garden. I made this recipe up as I went along so I don't really have exact measurements.

Zucchini and Yellow Squash
1 small Yellow Onion diced
butter
2 cups Chicken broth
1/2 cup heavy cream
juice of 1/2 a lemon
salt and pepper to taste

I melted butter in large pot added onion and sauteed until soft. Add sliced squash and cook for about 10 minutes over medium heat. Add broth salt and pepper and simmer until soft. I then added the squash with just a little bit of broth to my food processor and mixed until creamy. Return to pot and add heavy cream and lemon juice. I served the  soup with a dollop of sour cream an avocado slice and lemon zest. Delicious!!
