Flavorful Mahi Mahi Sheet Pan Dinner

Preheat the oven to 375 degrees F (190 degrees C). Spray a large sheet pan with cooking spray.

Mix green beans, olive oil, and seasoned salt together in a large bowl. Coat thoroughly. Place on one quarter of the sheet pan.

Bake in the preheated oven for 10 minutes.

While beans are baking, pat mahi mahi dry with a paper towel. Combine butter, lemon juice, and garlic in a small mixing bowl.

Toss green beans. Spray the empty side of the pan. Add tomatoes and onion; toss well. Place mahi mahi on top and brush with the lemon-garlic mixture. Season fish and tomatoes with salt and pepper.

Continue baking until fish flakes easily with a fork, about 25 minutes.
