These tasty meatloaves are just right for a busy family; serve them hot from the oven, at room temperature, or even chilled.
Preheat oven to 350 degrees. In a large skillet, heat oil over low heat. Add onion, carrot, and bell pepper; cook, stirring frequently, until tender, about 10 minutes.
Transfer vegetables to a large bowl. Crumble in bread; add milk and 2 tablespoons chili sauce. Stir to combine. Cool completely.
Add turkey, egg, and sage; season with 1 1/2 teaspoons salt and 3/4 teaspoon pepper. Using your hands, mix to combine. Divide into four equal parts. Gently shape each into a 3-by-4-by-2-inch loaf; place on a rimmed baking sheet.
Brush remaining 1/4 cup chili sauce over tops, dividing equally. Bake until meatloaves are cooked through, 35 to 40 minutes.
Tomato-based chili sauce is similar to ketchup but slightly spicy; you can find it with other condiments at your grocery store.
