Artificial Food Coloring Free Turmeric-Ginger Tuna Steaks with Tomatoes & Green Beans Sheet-Pan Dinner
Sheet-pan dinners are weeknight heroes, and this one earns its place at the top of the rotation with bold, warming spices and a lineup of whole, unprocessed ingredients. Every bit of color here comes from real food — the golden hue from ground turmeric, the deep warmth from smoked paprika and cumin, the bright pop of cherry tomatoes blistering in a hot oven. That matters a lot when you're avoiding synthetic dyes, because pre-seasoned fish and jarred spice blends are surprisingly common offenders hiding artificial colorants in their ingredient lists. Here, you mix the rub yourself from pantry staples, so you know exactly what's going on the plate. The tuna steaks roast alongside garlicky green beans and jammy tomatoes, picking up all that fragrant spice while the vegetables soften and caramelize around them. A squeeze of fresh lemon at the end cuts right through the richness and ties everything together. It's a genuinely impressive dinner that comes together on a single pan with zero fuss and nothing artificial in sight.
