Defrost frozen phyllo dough overnight in refreigerator.
Work with 1 sheet of phyllo at a time; cover the remaining phyllo with wax paper and a slightly damp paper towel on top of the wax paper.
Orient the sheet so it is "landscape" on a cutting board (or your work surface). Cut the sheet with a very sharp knife so that you have 3 pieces of phyllo, each measuring about 4-5" x 9".
Gently brush each sheet with melted butter.
Near the edge closeset to you, center a small "finger" of goat cheese (about 2-3 t.) and a small dollop of jam (about 1-2 t.) on the phyllo piece.
Gently roll the phyllo over the goat cheese-jam, like a little log.
Carefully fold the sides of the phyllo piece over the finger of goat cheese-jam, and continue rolling - like a little burrito.
Seal the outer edge of phyllo with a very small amount of melted butter and place the crouton-burrito on a parchment-lined baking sheet.
Repeat this rolling process about 53 more times, for a possible total of 54 croutons.
The croutons can be frozen at this point; freeze them initially on the baking sheet about 2 hours until very hard, then carefully pack in a gallon-size ziploc freezer bag and return to the freezer until you need them. To bake them from the freezer, do not defrost them but bake them frozen, in a 350° F oven for 20-30 mins.
To bake croutons as soon as they are rolled, bake them in a preheated 350° F oven for about 10 mins, or until glden brown.
