Fill a large pot up with water. Add carrot peels, excess ginger chunks, garlic cloves, 1 tsp black peppercorns, 3-4 bay leaves, 1/2 onion, salt, and chicken thighs to it. Bring to a boil and cook for 15-20 minutes or until chicken is fully cooked. Once fully cooked, wait for it to cool and shred it. Skip this step if you have pre-made, shredded chicken.
Prepare all of your stir fry vegetables. Heat oil up in a spacious pan and start by frying the garlic, onion, and ginger for 2-3 mins on medium heat, stirring frequently.
Next, add the sliced carrots and fry for 2 more mins.
Mix in the diced celery and sliced bell peppers last and fry for 2-3 more mins.
Once the vegetable mixture is golden brown, add in the shredded chicken. Season with salt, pepper, and red chili flakes.
Add soy sauce and mix well.
Cook for 3-5 more minutes and remove from heat. Allow chicken mixture to cool before making spring rolls.
Start forming spring rolls by dipping a rice paper wrapper in lukewarm water for 10-15 seconds.
Lay it on a slightly damp cutting board or flat surface. Add about a tablespoon of the chicken mixture close to the bottom half of the wrapper, leaving about an inch of space from the bottom.
Add in fresh jalapeño slices, some cilantro, and mint.
Roll the bottom part of the rice paper wrapper over the filling. Fold in the left and right side of the wrapper. Then, proceed to roll the bottom part all the way up until you have a roll.
If you want to fry the rolls, wet a second piece of rice paper and wrap everything again in a second sheet.
Once all of your rolls are ready, heat a neutral oil up in a frying pan to medium high heat. Fry each roll for 2-3 minutes on each side or until golden brown.
Serve with your favorite dipping sauce!
