Steps

• Step 1: Spray a medium-sized nonstick skillet with cooking spray. Heat skillet over medium heat and stir in onion; cook and stir until onion has softened and turned translucent, about 5 minutes.
• Step 2: Thinly slice sausage and then chop it into 1/4-inch cubes. Stir sausage into skillet with onions.
• Step 3: Stir tomato into sausage mixture and adjust heat to medium-high. Stir in chile pepper, if using. Mix in hot sauce. Cook, stirring occasionally, until tomatoes have broken down and most of the liquid has evaporated, 10 to 15 minutes.
• Step 4: Remove from heat and stir in lime juice. Serve warm.
