Wash and prep the zucchini, carrots, celery and potato.
Dice the onion and crush the garlic.
Saute the onion in 2 tbsp of olive oil and 1/2 tsp salt for 5 minutes in a soup pot.
Prep the chicken or vegetable broth. I boil water in a kettle, then add the water to a large 8 cup pyrex measuring cup, add powder broth as required and whisk to mix.
After 5 minutes of cooking the onion, add 1/2 to 1 tsp of butter, melt it and add the herb/spice blend #1. Toast the herb/spice blend for 2 minutes.
Add the garlic, stir for 30 seconds to 1 minute then drop in the celery and carrots and cook for 5 more minutes.
Throw in the zucchini cubes and cook another 10 minutes.
Pour in the broth, add the bay leaf, stir, cover and bring to a boil.
Turn down to a simmer and cook for 15 - 20 minutes or until veggies are soft enough to puree.
Remove from heat and take out the bay leaf. Puree the soup.
Add the lime juice and blend.
Temper the whipping cream, and pour into the soup. Blend till smooth.
Add salt and pepper to taste.
Top with shredded parmesan cheese and croutons and serve immediately.
