I found this recipe near the bulk cornmeal bin at WinCo. I really like it. There is no oil and just a touch of sweetness...
1 c. flour
1 c. cornmeal
1/4 c. sugar
1 tsp. baking soda
3/4 tsp. salt (I use just a little shake or none at all)
1 c. plain yogurt
2 eggs, beaten
Preheat oven to 400 degrees. Lightly grease an 8x8 inch baking pan (I disagree with this. For cornbread to be worth eating, you must cook it in an iron skillet! If you don't have one, go to an antique store or estate sale and pick one up for about $20.). Mix flour, cornmeal, sugar, soda, and salt in a large bowl. Stir in yogurt and eggs. Stir only until well blended. Pour batter into skillet. Bake for 20 to 25 minutes, until lightly golden.
