Creamy Guac

I found an old cookbook of mine that is full of blender recipes, and this guacamole is from the pages of that book - it's tasty!  And very creamy!

2 T lemon juice
3/4 tsp salt
1 small tomato cut in pieces
1/4 med onion
1 7oz can green chiles
2 ripe avocados halved, seeded, peeled, into chunks

Place everything in the blender and pulse til smooth - makes 2 cups.
