Chop onions , tomatoes, olives and jalapenos finely.
On a serving plate arrange nachos. Add onion, tomatoes, olives, jalapenos.
Squeeze lemon and add sour cream and cheese dip.
Notes
As this is a kids friendly dish I have not added any hot sauce. A little bit of jalapenos goes a long way. However for grown ups jalapenos and hot sauce can be adjusted.
