Place in a mini food processor/chopper: garlic, ginger, jalapeños. Pulse until finely diced. And add to the prep plate of sliced onions.
In the same emptied processor (no need to rinse), chop/puree fresh cilantro (twist off the woody stems, wash the rest and squeeze out water), throw in mini processor and add tomato wedges to make a cilantro/tomato sauce.
