Slice the shallots, garlic, and ginger. Crush the roasted peanuts until coarsely ground, not too fine. Finely chop the chicken breast.

Heat oil in a pan. Add the shallots, garlic, and ginger, and sauté until fragrant. Add the chopped chicken and cook until done. Season to taste and cook until the mixture thickens. Finally, add the peanuts and stir until dry. Let the mixture cool completely, then shape into small balls.

For the shallots, use small, round shallots about the size of a dime. Avoid large onions or tiny Thai shallots. I buy the round shallots, but I'm not sure what they're called.
