This is the ultimate flexible dish. Our Roasted Heirloom Tomatoes do triple-duty here: the tomatoes bring umami flavor; the liquid from the jar works perfectly in place of olive oil and vinegar; and the flavor punch means there's no need for additional salt and pepper. Substitute mushrooms for the cheese and the dish is Whole-30 compliant. Substitute mushrooms for the fish and you have a comforting vegetarian entree.

• Step 1

  Preheat oven to 350 degrees.

• Step 2

  Heat liquid from Roasted Tomatoes in a large skillet over medium heat. Add onions and cook for 3 minutes until they begin to soften.  Add spinach, Oven Roasted Heirloom Tomatoes, and red pepper flakes and cook an additional 2 minutes. Remove from heat and let cool slightly. Add ricotta and stir to combine. Season with additional juice from Roasted Tomatoes, to taste.

• Step 3

  Place salmon fillets in a glass baking dish, spoon tomato-spinach mixture over fish, and bake for 15-20 minutes, until salmon is cooked through.
