As meals go, breakfast typically is the least expensive of the day. Eggs, bread and milk are relatively cheap and with the right recipe can become more than the usual omelettes and toast. Oven-baked French toast with mixed berry sauce is inexpensive to prepare and is impressive enough for company, yet simple enough to make for a Sunday brunch with family. The easy-to-make-sauce uses inexpensive frozen mixed berries, but the recipe is flexible. An equal amount of any frozen berries can be substituted. The sauce will keep, in an airtight container, for up to a week.
