Heat a grill to a high.
Drizzle onions, jalapeño, tomatoes and avocados with olive oil. Once grill is hot, place everything onto a grill cut-side down and grill until charred. Remove from grill and cool.
Once cool, chop onions and place into a bowl with lime juice and salt. Let sit for a few minutes.
Meanwhile, chop jalapeño and tomato. Add to bowl with onions. Add in the avocado and mash to desired consistency. Stir in cilantro to taste.
