I'm assuming you are looking at Protein Equivalency Chart A?

1 egg plus 2 egg whites plus 1 oz of meat is equivalent to just about 20 grams of protein (1 meal serving if you are budgeted for 60 grams of protein per day)

The chart is just an example to show what you would eat per meal in protein at that level of 60 grams protein per day.

There's nothing wrong with eating one egg or two eggs or 3 eggs.

1 whole egg is roughly 6 grams protein
