Prepare vegetables to roughly a 1/2-inch dice, with exception of 1-inch diced potatoes. Mince garlic, and dice leftover, cooked salmon filet into 1-inch cubes.
Heat olive oil in a medium pan over high heat. Once heated, add onion, bell pepper, carrot and celery, stirring to cook for about 5 minutes. Once onions are translucent, add in garlic and diced potatoes. Cook for an additional 1 minute.
Add vegetable broth to the pan and bring to a boil. Once boiling, reduce heat to simmer for about 10 minutes, until potatoes are just cooked through.
Pour in coconut milk and stir to combine. Bring back to a simmer, and add in diced, cooked salmon. Cook for about 3 minutes, until salmon is warmed. Taste and add additional salt and pepper to taste.
A Seasoning Note: I don’t add salt and pepper in advance, because my roasted salmon is already well seasoned. This keeps me from having an overly salty chowder.
