Boil pasta according to directions on the package, about 9 minutes. Drain, and let cool. Stir occasionally while cooling to separate pasta.
Meanwhile, rinse all the vegetables.
Open olive jars and can and drain olives.
Slice the pimento stuffed olives.
Cut broccoli into small florets.
Dice the yellow, orange, and red sweet peppers.
When the pasta is cool, you can combine all ingredients, and stir gently. This makes a huge batch, so I had to use two of my largest bowls. I divided the pasta between the two bowls, and then divided all the ingredients between the two bowls.
You can make this a day ahead, and refrigerate.
