The key of good nasi lalapan is the sambal terasi/belacan.

In Indonesia especially Central and East Java, we called this kinda dish Pecel/Pecak Ayam.
We identify this kinda food with the meat it uses: Pecel Ayam using Fried (Ayam Goreng) or grilled (ayam bakar) chicken. Pecel Lele (fried catfish), or fishes (Ikan Bawal Bakar).

Pecel Ayam

Pecel Lele
While in West Java, home of Lalapan, lalapan was originally consists of assorted raw vegetables and sambal terasi.
Lalapan (or lalaban in original Sundanese) is raw or semi-cooked vegetables, actually considered as side dish to accompany the meats and completed with sambals.


Original lalapan..., no meats, just sambal with fresh veggies

Various vegetables that can be used as lalapan
All ethnicities in Indonesia knows and gave credit to Sundanese people as the inventor and home of Lalaban.
Just as Rendang belongs to Padang/Minangkabau people, or satay that closely associated with Madurese people.
Here we go..., rendang, satay, nasi lalapan; the lists is gettin' longer and longer

Well at least they credited Indonesia this time.
I wonder will Garuda Indonesia serve Nasi Lemak and Teh Tarik.
