Cod Fillets with Tomatoes andZucchini
The flavors here are sort of like ratatouille, but minus the eggplant. However, the final consistency of the vegetables surrounding the fish is more like a sauce because the vegetables are just about melted down by the pot’s pressure in the two-step cooking process. If you find the sauce is too thin after cooking, remove the fish from the pot and boil the sauce down with the SAUTÉ function on MEDIUM, NORMAL, or CUSTOM 300°F for a few minutes. Even so, we find that a little bit of, well, wateriness in the sauce brings a lightness to the overall dish. One note: It may seem strange, particularly in an 8-quart cooker, that there’s no additional liquid with the tomatoes and other vegetables. The zucchini will throw off so much liquid that the pot will come to pressure without any burn notice. Just remember to use only diced tomatoes packed in juice.

Recipe Notes

Beyond
• If you don’t want to use a Provençal or Mediterranean seasoning blend, substitute 1 teaspoon lemon pepper seasoning, 1 teaspoon dried marjoram, and 1 teaspoondried thyme.
• Garnish each serving with 1 tablespoon butter or a generous drizzle of extravirgin olive oil.
• Substitute four frozen 6-ounce halibut or tilapia fillets for the cod.
• Garnish with finely grated lemon zest and/or drained and rinsed capers. Or skip those and garnish each serving with a little tapenade. And don’t forget garlic toast!
