Grilled Fish with Sweet Potato Mash

Sweet potatoes mash down into something naturally creamy without needing much butter or cream, which is exactly what happens here — just a splash of almond milk and a little olive oil to loosen them up.

The fish cooks alongside on a hot grill pan, needing only a few minutes a side once it's rubbed with olive oil, lemon juice, and a light seasoning of salt and pepper. Lean white fish and orange-fleshed sweet potatoes are the kind of straightforward, whole-food pairing that tends to fit comfortably into a thyroid-conscious diet.
