In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add finely chopped onion, yellow pepper, and guindilla verde pepper. Sauté for about 3–4 minutes until the onions become translucent and the peppers are tender.

In the same skillet, add the extra lean ground beef, crumbling it as you go. Cook over medium-high heat for approximately 5–7 minutes until it turns browned.

Preheat your oven to 350°F (175°C).

In a mixing bowl, combine the cooled beef and vegetable mixture with chopped green onions and Neufchâtel cheese. Mix well until all ingredients are nicely blended.

Roll out your crescent roll containers. Place a generous tablespoon of the beef-cheese mixture at the broader end of each triangle.

Sprinkle a small handful of shredded sharp cheddar cheese over the filling in each crescent triangle. Starting from the wider side, roll up each triangle tightly.

Arrange the rolled-ups on your prepared baking sheet and bake for about 15 minutes, or until golden brown.

Remove the Cheesy Beefy Roll-Ups from the oven and let them cool slightly on a wire rack. Serve warm with salsa or sour cream.
