Not quite guacamole, though I'll mention it.
Single serving:
1 ripe avocado, cubed
Lemon or Lime juice splashed
1/2 green onion/scallion
hefty teaspoon mayo
light dusting of paprika
light dusting of salt
Mush it all up and dip it with tortilla chips.

Yum
(Finely diced tomato would also be good mixed in, but then I want to add a teensy bit of garlic.)
Upgrade to guacamole:
Add
Small jalapeno pepper, finely diced
Tablespoon cilantro
Dusting of chili powder and a tiny smidge cumin
(Multiply ingredients per number of servings.)
