Preheat your oven to 400°F and line a small baking sheet with parchment paper.
In a small bowl, whisk together the dried oregano, dried thyme, sea salt, black pepper, and garlic powder.
Brush the salmon fillet with one teaspoon of the olive oil, then press the herb mixture firmly onto the top of the fish to create a crust.
Place the salmon on the prepared baking sheet and roast for 12 to 15 minutes, or until the fish is opaque and flakes easily with a fork.
While the salmon is roasting, heat the remaining teaspoon of olive oil in a large skillet over medium heat and sauté the minced garlic for about 1 minute until fragrant.
Add the chopped kale and vegetable broth to the skillet, cover with a tight-fitting lid, and braise for 4 to 5 minutes until the leaves are tender and bright green.
Remove the lid, stir in the lemon juice to brighten the flavors, and serve the salmon immediately over the bed of braised kale.
