Place salmon on a lined baking sheet and sprinkle with a touch of olive oil, salt, and pepper. Bake 10-12 minutes or until cooked through and flaky.
Bring a small pan to medium high heat and add 1 Tbsp olive oil and 1 Tbsp of the butter. Add shallots when butter is melted and cook ~ 3 minutes or until soft.
Add wine, bring to a boil and simmer uncovered until reduced by half (~ 3-4 minutes).
Reduce heat to low and whisk in mustard, 1 1/2 Tbsp dill, salt, and pepper.
Remove pan from heat. Add remaining 2 Tbsp butter and whisk into sauce.
Add salt to sauce to taste.
Plate raw zoodles and top with baked salmon. Drizzle on dill butter sauce.
Garnish with remaining dill. Happy eating! Beckie
Notes
Don't burn the shallots. They should be soft and translucent, not crispy. Reduce the heat if they are starting to crisp up.
