In a pot with salted water, place the meat, carrots and potatoes and let them cook until they are fork tender. The potatoes and carrots will be ready before the meat, so be sure you're checking once in a while.
After they're cooked, drain and let them cool.
Chop into dices the meat, potatoes, carrots and pickles.
Into a big bowl, add the meat and all the vegetables, including the peas and ½ cup of mayonnaise. Season with pepper and salt and mix it all together.
