Coat a large skillet with cooking spray; place over medium-high heat. In a bowl, beat together eggs, egg whites, scallions, cilantro, salt and pepper until blended; pour into skillet and scramble just until barely set, about 2 1/2 minutes (egg mixture should still be slightly wet; be careful not to overcook).
Remove from heat and gently fold in salsa.
Place 1/6 of eggs on top of each muffin bottom. Top with muffin tops. Yields 1 sandwich per serving.
Want to eat it on the run? Wrap it up in whole grain flour tortilla and make a breakfast burrito instead (might affect SmartPoints value). Add fresh sliced tomato, sliced water-packed roasted red peppers and/or jalapeno slices, if desired.
