Serves: 8 servings, generous 1/2 cup filling each
12 ounces 90%-lean ground beef
1 each large onion , finely diced
2 cups finely chopped Cremini mushrooms (about 4 ounces)
5 each plum tomatoes , diced
2 tablespoons all-purpose flour
1/2 cup water
1/4 cup cider vinegar
1/4 cup chili sauce , such as Heinz
1/4 cup ketchup
8 each whole-wheat hamburger buns , toasted if desired
1: Crumble beef into a large nonstick skillet; cook over medium heat until it starts to sizzle, about 1 minute. Add onion and mushrooms and cook, stirring occasionally, breaking up the meat with a wooden spoon, until the vegetables are soft and the moisture has evaporated, 8 to 10 minutes.
2: Add tomatoes and flour; stir to combine. Stir in water, vinegar, chili sauce and ketchup and bring to a simmer, stirring often. Reduce heat to a low simmer and cook, stirring occasionally, until the sauce is thickened and the onion is very tender, 8 to 10 minutes. Serve warm on buns.
