One of my bad habits is that once I start working on anything, I tend to be unable to stop until I finish it all. So I often had a late lunch. Not a healthy habit, I know.
Living in a dense area with a university right behind my kitchen, eating places swarm around my neighborhood like ants to candy. I could easily buy whatever I want for my meal, and I do, from two of them which had passed my inspection as being healthy enough, descent enough, and hygienic enough to eat. Although sometimes I'm not really sure about the latter. I usually was exhausted from work, so I just let go. As long as it has enough raw vegetables and is sold in a house, not by the street where carbon monoxide is expected to be all over, I can live with it.
But when I have the energy to prepare my meal, and I often do, I just open my fridge and improvise from there. One afternoon, I had all these beautiful free range eggs, grainy mustard, gorgeous red and green veggies, and I was sold. Turned them into a delish omelette and red-green salad, and I had a beautiful healthy late lunch.
The name Bang-Jo salad I got from when I was on a trip to Jepara and was looking for a direction. A man said, "Go straight until the bang-jo." I frowned. Later I found out that bang-jo was a short for abang-ijo, means red-green in Javanese, means traffic light. :)
