White sauce can be used on almost anything from meat and fish to vegetables. Put it on eggs. Add a half cup of grated cheese at the end and turn this into a cheese sauce. Chop an onion and saute it in butter for 10 to 15 minutes and add to the basic white sauce to make an onion sauce. The basic sauce can be made in less than 5 minutes. Make it ahead of time. It will keep in the refrigerator for about a week.
