Cut the avocados in 1/2, remove the pits, and scoop the flesh out of their shells into a large bowl. (I use my hands.) Immediately add the lemon juice, hot pepper sauce, onion, garlic, salt, and pepper and toss well. Using a sharp knife, slice through the avocados in the bowl until they are finely diced. Add the tomatoes. Mix well and taste for salt and pepper.
