In a medium-size skillet over medium-low heat, add 1 tablespoon of olive oil. Once hot, add the 2 cloves garlic and cook until fragrant, 30 seconds, stirring constantly.

Place one sheet of the p8 sheets phyllo dough on a clean work surface. Brush highly with the remaining olive oil, add another sheet on top, brush with olive oil, repeat until you have four sheets layered.
Cut the dough into 6 evenly sized sections. To do this, cut three strips lengthwise, then cut them in half.
To make the bundles, add about 1 tablespoon of the filling at the phyllo dough strips’ bottom. Fold the dough over to format triangle, continue to roll the triangle repeatedly until you form a little pouch, and make sure that the is a little excess dough at the top to seal the edge.
Repeat with the remaining phyllo sheets and filling.
