The cooking time will vary depending on whether the veggies are fresh, canned or frozen.
Using a large saucepan, saute the onions, carrots, celery and garlic in a small amount of olive oil until softened.
Add the broth and the peas and continue to cook at a simmer. Season with salt and pepper.
If using fresh peas, you may see some scum forming. Spoon that off.
When the vegetables are all cooked through, stir in the chopped mint.
Use an immersion blender to puree the vegetables. Taste and adjust the seasoning.
Stir in the cream and serve with a garnish of mint leaves.
