1 cup thinly sliced Celery
1 Tablespoon minced Jalapeno peppers, or diced mild chili peppers
2 cloves Garlic (finely minced)
1 can (14.5 ounces) diced Tomatoes (undrained)
2 cups cooked Sweet corn (frozen corn may also be used, or 1 can of corn may be substituted)
1 teaspoon Chili powder
1/2 teaspoon Salt
Dash Pepper
1/2 teaspoon ground Cumin
4 medium Potatoes (peeled, thinly sliced, about 1 1/2 to 2 pounds)

2. Grease a 9-by-13-by-2-inch baking pan (2 1/2 to 3-quart size).
3. Heat the olive oil in a large skillet over medium heat.
4. When the oil is hot and shimmering, add the ground beef, onions, and celery.
5. Cook until beef is browned and vegetables are tender, stirring frequently.
