Preheat the oven to 425°F. Line a baking sheet with parchment paper or a silicone liner.
In a large bowl, whisk together the olive oil, balsamic vinegar, garlic, tamari, and pepper.
2 teaspoons olive oil, 2 tablespoons balsamic vinegar, 3 cloves garlic, 1 teaspoon low-sodium tamari, freshly ground black pepper
Add the bell peppers, eggplant, yellow squash, and butternut squash. Toss until the vegetables are well-coated, then pour the mixture onto the prepared baking sheet.
1 medium red bell pepper, 1 medium Asian-style (skinny) eggplant, 1 medium yellow squash, 1½ cups butternut squash
Season the salmon with garlic pepper.
4 salmon fillets, garlic pepper
Place the pan in the oven and roast the vegetables for about 3 minutes.
Remove the pan from the oven, add the salmon on top of the vegetables, then return to the oven.
Continue roasting until the salmon is cooked through and the vegetables are tender, about 12 minutes.
