Halibut in Hazelnut Romesco with Potatoes
A traditional Spanish romesco sauce calls for almonds, but in this recipe hazelnuts spruce up simple halibut fillets. The sauce freezes well and also partners with chicken, steak, or pasta. For a more budget-friendly dish, substitute tilapia. You can also swap roasted red peppers for the piquillos and use whatever nuts you happen to have in the pantry.
