Heat the oil in a large skillet. Add sausage and crumble. Saute over medium heat until cooked through.
Add pasta sauce, water, and peas and bring to a boil.
Pour into a pie plate.
Unroll and separate breadsticks. Place 6 of the breadsticks across the pie plate over the sausage mixture, twisting each one and spacing evenly. Place the remaining 6 breadsticks over the first in the opposite direction, creating a lattice pattern. Trim ends if needed.
