Eggs are a wonderfully versatile and inexpensive ingredient. They’re an excellent source of protein, but the quality and freshness of the eggs are very important. This egg and biscuit sandwich with chipotle Hollandaise sauce makes a stupendous Sunday brunch or breakfast. Soft avocado purée over warm biscuits, topped with crunchy bacon and delicious egg. The chipotle sauce is a little spicy, but combines well with the creamy avocado and the richness of the egg yolk.
