Preheat oven to 425 degrees. In a large pan, drizzle the bottom with avocado oil, add garlic and red chili sauté for a minute or two until soft and fragrant.
Add in fennel seeds, and sprinkle with salt and pepper. Add fennel slices, and sauté for a few minutes.
Add tomatoes and let the mixture simmer for two to three minutes or until the veggies are soft. Sprinkle salmon with salt and pepper and drizzle the top with avocado or olive oil.
Place salmon in the pan and the mixture in the oven for 15 minutes. You can drizzle with extra avocado, oil, garlic, and paprika if desired when the mixture is done.
