New potatoes and peas play a starring role in this fabulous vegetable dish. The creamy potatoes and peas go well with just about any meat, fish, poultry, or seafood. If the season isn't right for new potatoes, go ahead and use "Baby" Potatoes, fingerlings, or cut-up red-skinned or yukon gold potatoes. If you're making the dish for a special dinner or holiday meal, a combination of baby red and white pearl onions makes an attractive presentation. Fresh peas are amazing in this dish, but feel free to use good quality frozen peas.
