Pat your sirloin or ribeye steak dry with paper towels. Rub with olive oil and season with salt, black pepper, garlic powder, and smoked paprika. Let rest for 20 minutes.

Preheat your grill or grill pan to high heat, around 450°F to 500°F. Add olive oil if using a grill pan.

Slice zucchini into rounds or planks, brush with olive oil, and sprinkle with salt. Grill for 2–3 minutes per side until tender.

Grill seasoned steak for 4–5 minutes per side for medium-rare, or until a meat thermometer reads 130°F. Let rest for 5 minutes.

Prepare cooked grains according to package instructions. Fluff with a fork once cooked.

In a bowl, mix sour cream or Greek yogurt with Dijon mustard, garlic powder, smoked paprika, and salt. Stir until smooth.

Assemble the bowl starting with grains, then layer with grilled zucchini and sliced steak. Drizzle creamy sauce over the top.
