Drain tomatoes and roughly chop. Mix with the goat cheese. Spread 1/4 cup goat cheese mix down the center third of each of the tortillas. Arrange the slices of julienne chicken breasts and 1/4 of the avocado slices over the goat cheese. Spoon a 1/4 cup of the salsa over the chicken and avocado slices. Add the mixed salad greens on top of the salsa, use enough to cover all the chicken mixture. Add the BBQ sauce to your liking. Roll up each tortilla and slice in half.
