Bring 4 cups water to a boil in a saucepan over high heat. Add rice, reduce heat to a simmer and cook for about 20 minutes, or until the rice has absorbed all the water.
In a large skillet, cook bacon over medium heat until crispy. Set aside on paper towels. Reserve drippings in skillet.
To the skillet add onions and cook over medium heat, for 3 to 4 minutes, or until tender. Add black-eyed peas, corn, lima beans, and chicken broth. Bring to a boil, cover, reduce heat, and simmer for 30 minutes, or until vegetables are tender; drain. Place into a large bowl.
In a small bowl, whisk oil, vinegar, seasoned salt, and pepper. Pour on top of vegetable mixture and toss to coat. Mix in rice and crumble in the reserved bacon. Cover and chill in refrigerator for a few hours before serving.
