Heat oven to 400ºF.  Cook and stir ground beef over medium heat until light brown; drain. Place beef in ungreased baking dish, 11 3/4 x 7 1/2 x 1 3/4 inches. Stir in onion, chili powder, oregano, soup, carrots and corn. Drop Sesame Topping by teaspoonfuls around edges of baking dish. Bake uncovered until topping is golden brown, about 15 minutes. 6 servings. 

SESAME TOPPING:

1 cup of biscuit baking mix
1/4 cup of butter or margarine, softened
3 tablespoons of boiling water
2 tablespoons of sesame seed

Mix all ingredients until a soft dough forms. S-t-r-e-e-t-c-h it two ways! You can make Sesame Topping double as a pie crust. Pat the dough with floured hands into a 9 inch pie plate, bringing the pastry to the edge of the pan. Flute the edge if you like; do not prick. Bake in a 450ºF. oven for 10 minutes. Cool, and it's ready for your favorite filling.
