These were delicious! I made a few changes to the recipe, which I've highlighted in purple below. Joe really liked them, too, so I'm sure I'll be making them again!

1/3 pound bulk pork sausage (I used spicy sausage)
2 tablespoons sour cream
2 tablespoons half-and-half (I didn't have any, so I used 1 tablespoon of milk and 1 tablespoon of heavy cream)
1 package taco seasoning mix (I substituted 1 tablespoon of Emeril's Southwest seasoning)
1 tablespoon butter or margarine
2 tablespoons finely chopped fresh chives
2 tablespoons finely chopped fresh cilantro (I used a dash of dried; it would have been better with fresh, but I didn't have any)
2 tablespoons chopped tomato
1 can chopped green chiles (I omitted because I thought it would be too spicy with the hot sausage and pepper-jack cheese, but I'll add them next time I make these)
1 package flour tortillas, burrito size
1/2 cup shredded cheddar cheese
1/2 cup shredded Monterey jack cheese (I used pepper-jack cheese)
1. In a skillet, cook sausage over medium heat, stirring frequently, until browned and no longer pink. Remove sausage from skillet; drain on paper towels. Meanwhile, in medium bowl, lightly beat eggs, sour cream, half-and-half and seasoning mix with wire whisk until well-blended.
2. In a separate nonstick skillet, melt butter over medium heat. Add egg mixture; cook 2 to 4 minutes, stirring frequently, until mixture is very moist. Stir in cooked sausage, chives, cilantro, the tomato and chiles. Cook 1 to 2 minutes longer or until egg mixture is set but still moist. Remove from heat.
3. Place tortillas on work surface. Top half of each tortilla with 2 to 3 tablespoons egg mixture; sprinkle each with 1 tablespoon of each of the cheeses. Fold untopped half of tortillas over egg mixture.
4. Heat a 12-inch skillet (or griddle) over medium heat. Place quesadillas in skillet; cook 30 to 45 seconds on each side or until crisp and lightly browned. Remove from skillet; place on serving plate. Cut each quesadilla into wedges. Top with chives, salsa, sour cream, or avocado, if desired.
