5. 5
   Put the half-and-half and butter in a microwave-safe container and microwave until warm, about 35 seconds.
6. 6
   Drain the potatoes and return them, off the heat, to the warm saucepan.

    Heat the oven to 400F.
11. 11
    In a large skillet set over medium-high heat, heat the oil until it shimmers.
12. 12
    Add the onion, bell pepper, and carrots and cook, stirring, just until they begin to take on color, 3 to 4 minutes.

    Stir in the corn and peas.
19. 19
    Spread the vegetable mixture evenly into an 11 x 7-inch glass baking dish.

    Top with the mashed potatoes, starting around the edges to create a seal to prevent the mixture from bubbling up, and smooth with a rubber spatula.

    Bake on the middle rack of the oven for 25 minutes or just until the potatoes begin to brown.
