This moist, hearty bread slices beautifully for sandwiches or toast. The dough is sticky because of the moisture from the cooked quinoa, but resist the urge to add too much flour.
03Punch down the dough, cover the bowl and allow the dough to rise again for 45 minutes to an hour.
04Preheat the oven to 375 degrees. Divide the dough into two parts, and shape into loaves. Place half of the sesame seeds on your work surface, and gently roll the rounded side of one loaf over them so that they stick. Repeat with the remaining sesame seeds and the other loaf. Oil two 9-by-5-inch bread pans, and place the loaves in the pans, first seam side up, then seam side down. Cover with a damp towel and allow to rise for 30 minutes, or until the surface of the loaves rises above the edges of the bread pans.
05Gently brush the loaves with egg wash. Using a sharp knife, cut two or three 1/2-inch-deep slashes across the top of each loaf. (If this causes the loaves to deflate, let them sit for another 15 to 20 minutes.) Bake 50 to 55 minutes, brushing again halfway through with egg wash. The bread is done when it is golden brown and responds to tapping with a hollow sound. Remove from the pans and cool on a rack.
