Prepare one brik at a time.
In a deep-frying pan, warm oil on medium heat to 350°F.
Carefully place the blanched asparagus, a couple of avocado slices and an egg on the top center part of the brik dough.
Gently fold the top part of the dough forward, tuck the sides in and continue to fold the dough over the filling.
The egg white will help the dough sheet stick together.
Place the folded brik aside and set on parchment paper.
Continue folding all briks using the same method.
Once all briks are folded, carefully drop them seam-down into the hot oil.
Make sure not to fry more than a couple at a time in order to keep the oil temperature steady.
Fry for one minute on both sides until the brik is golden brown.
For firm yolks you may add another minute of frying time.
Remove briks, place on a paper towel and dust with cumin and salt.
Serve along with harissa. (Find a recipe for harissa on afooda.com)
