For the crust. In a large bow, mix the dry ingredients and stir with a fork, slowly drizzling in the olive oil. Then slowly add the warm water and knead by hand until you get a firm and moist dough. Form into a ball, then place it back into the bowl with a moist towel covering the top, and return to the refrigerator.
The chicken. In a frying pan, brown your chicken tenders by coating the pan with a tablespoon of vegetable oil. Any non meat chicken substitute works well. When done, place on paper towel to drain. When cooled, cut into bite size chunks.
The filling. Bring broth to a boil in a large saucepan, turn the heat to medium low and sift the flour in while whisking to keep from getting lumps. When all the flour is in, turn the heat off and mix in the vegetables and dry ingredients, then set to the side.
Preheat oven to 400°.
Time to build. Using a 9 inch pie plate, or a spring form pan, oil the pan or plate and dust with flour. Take the dough and roll out 3/4 of it to cover the pie plate. Place 1/2 of the filling into the pie, then spread the bite size chicken pieces over the top, and then add the rest of the filling. Next, roll out the remaining 1/4 portion of the dough to make the top covering, and lay it over the top. Fold the edges over and press to seal. Cut vent holes with a knife into the top, and bake at 400° for 30 to 40 minutes, or until crust is golden brown and dry to the touch. Take the pie out of the oven, and allow it set for about 5 minutes or longer to let the gravy thicken up.
