Heat olive oil in a medium sized pan over medium/high heat.
Add the chicken breasts and cook approximately 4-6 minutes per side (depending on thickness). Chicken is done when it reaches 165-170°.
Remove chicken from pan and shred. Keep warm.
Heat another drizzle of oil in the same pan and add the peppers and onions. Season with salt and pepper. Sauté until the peppers have softened to desired consistency, stirring frequently.
Add the chicken back into the pan.
Add entire package of taco seasoning and water. Stir to combine and remove from heat.
In a small bowl, combine ¼ c. sour cream and the juice and zest of one lime. Stir to combine.
Place tortillas on a plate with a damp paper towel and microwave for about 30 seconds to warm.
Fill tortillas with chicken mixture and top with a drizzle of lime crema. Top with pickled jalapeños.
