Follow these simple steps to create your Cowboy Queso:

1. Cook the Sausage: In a large skillet over medium heat, cook the ground sausage until browned and fully cooked. Drain excess fat if necessary.

2. Add Vegetables: Stir in diced bell peppers and cook for about 3-4 minutes, or until softened.

3. Mix in Tomatoes: Add the canned tomatoes (including juices) to the skillet. Stir well to combine.

4. Incorporate Cheeses: Reduce the heat to low. Add the cream cheese and shredded cheddar cheese. Stir until the cheese is melted and smooth.

5. Adjust Consistency: Gradually add milk to achieve the desired dip consistency. Stir until combined.

6. Season the Mixture: Add garlic powder, onion powder, cumin, salt, and pepper. Mix thoroughly and let cook for an additional 2-3 minutes.

7. Taste and Adjust: Taste the queso and adjust seasoning as necessary.

8. Serve: Remove from heat and transfer to a serving bowl. Garnish with jalapeños, cilantro, or green onions if desired.
