Although mustard is indispensable in the process of making olives, olives are not exactly the same as mustard. Because olive vegetables have green olives besides mustard.
Speaking of the cooking of olive vegetables, it can be traced back to a long time ago. Perhaps it was a coincidence that olive growers felt sorry when they saw a lot of green olives scattered on the ground, and then they took them back and cooked them with pickles. Unexpectedly, they cooked a delicious meal. Nowadays, the production technology of olive vegetables is very mature.
