Scrambling the eggs:

• Break 2 eggs into a bowl.   Add 2-3 tbsp of milk or cream to the eggs.  Whisk until combined.  Heat a small skillet over medium/high heat.  Add a pat of butter and let it melt.  Once it has melted, pour in the egg mixture.  Season with a good pinch of salt and pepper.Let the eggs sit until they begin to form curds and then gently stir.  When the eggs are mostly scrambled but still a little wet, take them off the heat and transfer to a plate or bowl. 
•  Brown the sausage (or if you're really in a hurry and want to make it even easier, buy the pre-cooked, crumbled sausage). 
• Wipe out the skillet you used for the eggs, turn on low-medium heat, and add a pat of butter to the pan.  Once the butter has melted, place one medium flour tortilla in the pan. 
• Top half the tortilla with shredded cheddar or Mexican blend cheese.   Add the scrambled eggs and sausage and top with more cheese.   Fold the other side of the tortilla over the ingredients and let it cook. 
• Flip the quesadilla over to brown the other side.  Cut into slices and enjoy!
