Preheat the oven to 400 degrees . In a small saucepan, heat the olive oil over medium heat. Add the scallion whites and 1/2 teaspoon salt and cook, stirring, for 1 minute. Stir in the rice to coat. Add 1 3/4 cups water and bring to a boil. Cover the pot, lower the heat and simmer until tender, about 30 minutes.
Meanwhile, line a baking sheet with parchment paper. In a medium bowl, beat together the tortilla chip crumbs, salsa, egg, 1/2 teaspoon salt and 1/4 teaspoon pepper. Mix in the ground beef. Place a 3--- to 4-inch heart-shaped cookie cutter on the prepared baking sheet. Press one-quarter of the meat mixture evenly into the cookie cutter; remove the cutter. Repeat with the remaining meat mixture. Bake until firm to the touch, about 15 minutes.
Stir the beans and scallion greens into the rice and season with salt. Serve with the mini meatloaves and extra salsa on the side.
