1. Start by heating a large skillet over medium heat. Add the lean ground beef and cook, breaking it up with a wooden spoon, until it’s no longer pink. Drain any excess fat from the pan.

2. Next, stir in the taco seasoning and the undrained can of diced tomatoes with green chiles. Let the mixture simmer for 5-7 minutes, until it thickens slightly. Remove the pan from the heat.

3. Preheat your oven according to the instructions on the package of frozen phyllo tart shells, usually around 375°F (190°C). Arrange the tart shells on a baking sheet, ready to be filled.

4. Using a spoon, scoop a heaping tablespoon of the taco beef mixture into each phyllo tart shell. Top each bite with a generous sprinkle of shredded cheddar cheese.

5. Pop the tray of assembled Taco Ranch Bites into the preheated oven and bake for 8-10 minutes, or until the cheese is melted and the tart shells are crisp and golden brown.

6. Remove the Taco Ranch Bites from the oven and drizzle them lightly with the ranch dressing. Serve the warm, cheesy bites immediately, and watch them disappear in no time!
