Hazelnut Free Mediterranean Tuna Steaks with Tomatoes, Olives & Green Beans
Bold, briny, and built entirely on pantry staples and fresh produce, this sheet pan dinner is the kind of weeknight meal that looks like you tried way harder than you did. Thick tuna steaks get rubbed down with a garlicky paste of oregano, smoked paprika, cumin, and lemon zest before roasting alongside blistered cherry tomatoes, tender green beans, and salty Kalamata olives — it's a full Mediterranean spread on a single pan. For anyone navigating tree nut allergies, this recipe is naturally in the clear: every ingredient is straightforward and easy to verify, with no sauces, dressings, or spice blends that might sneak in unwanted allergens. The technique is smart, too — the vegetables get a head start in the oven so everything finishes at the same time, and a final squeeze of fresh lemon ties the whole dish together. Cleanup is minimal, flavor is maximum, and the parsley scattered over the top at the end adds a pop of color that makes it feel genuinely restaurant-worthy. Whether you're cooking for a crowd or just treating yourself to something a little special on a Tuesday, this one earns a permanent spot in the rotation.
