Jalapeño Pepper

 is a consumable item in Fallout: New Vegas. Jalapeño Peppers can be obtained from Jalapeño plants.

It is also one of the ingredients used in making a Gecko kebab and Cook-Cook's Fiend Stew at a campfire.

Locations
Found mostly out in the Mojave Wasteland. There are many in the White Glove Society kitchen.

A few plants can be found south of Lone Wolf Radio and south of Gun Runners.

There are at least 9 plants in the El Dorado Dry Lake.

They can also be found in any windy desert area such as the desert area south of Primm, Ivanpah Dry Lake & Ivanpah Race Track which are both close to the same location.

Characteristics
Jalepeño peppers have an exceptionally low weight despite restoring the same amount of health as standard food items, making them exceptionally practical for healing minor injuries.

Like all other Mojave Wasteland plants, ripe Jalepeño plants found in the wasteland will eventually regrow after being picked by the player; making them an unlimited supply of free food.
