Cambodian Meatball Sandwich

This is my sister's version of the num pang: it is basically a Cambodian version of the bahn mi! One of my favorite sandwiches! Since it comes from my sister, there is one slight problem with it: no measurements! They do everything to taste, so experiment away. Really. Once you get the hang of making it, it's not very intimidating at all!

INGREDIENTS:
Meatballs
1 lb ground beef (or veal)
fresh breadcrumbs
1-2 eggs
1/2 onion (diced and sauteed a bit)
1-2 cloves garlic (minced)
Cilantro
Thai basil
Salt
Pepper
Spicy Mayo
Mayo
Sriracha
Honey
Salt
Pepper
Pickled Carrots
Shredded Carrots
Salt
Sugar
White Vinegar
Other Toppings
Good-quality, chewy french loaf
Cilantro
Sliced cucumber

DIRECTIONS:
1. To make the meatballs:  combine the meat with the garlic, onion, chopped cilantro, chopped basil, salt and pepper.  (All of this is to taste!  Depending on your taste buds, you can go heavier or lighter on the spices.  Don't overwhelm the meatballs with it, though!)  Add in enough breadcrumbs and eggs to make it moist and sticky.  I like to use 2 eggs, since it makes the meatballs very light and fluffy!  However, if you like heavier meatballs, only use 1 egg.
2. To form/cook the meatballs:  Don't over-mix the meatball mixture, but make sure everything's evenly dispersed.  Form into small meatballs.  I find that just a bit smaller than golf-ball-size works best for me.  Place on a baking sheet and bake at 350* until done.
3. For the spicy mayo:  Mix together mayo with a bit of salt and pepper.  (Not too much!)  Add in a few drizzles of honey and a few drizzles of sriracha.  Adjust to taste.  (More sriracha = more heat.  If you do too much, add more mayo or honey.)
4. For the picked carrots:  You're going to want to give these a chance to sit out.  Half an hour works fine, an hour's better, and overnight's best.  Mix white vinegar (maybe 1-2 cups) with a decent amount of sugar (maybe 1/4 cup).  Add in salt (a decent amount), then stir to mix.  Add in about 1-2 cups of shredded carrots.  Make sure most of the carrots are covered in the vinegar!  Let it sit out on the counter up to 2 hours, or in the fridge if longer.  These are ADDICTING and can be used on any sandwich!
5. To assemble the sandwich:  Warm up the bread just a bit.  I like to pick out the inside of the bread, so that I have room for my sandwich innards.  Put spicy mayo on top and bottom.  Put meatballs on the bottom part of the bread.  Add on pickled carrots, cucumber, and cilantro.  Put together and enjoy!!
