Here's the recipe I got out of the Frugal Gourmet Cooks American long ago, and it's still my favorite, though I do add chopped jalapenos (medium spicy ones) now and then:

3/4 c. flour
1 1/2 c. cornmeal
4 tsp. baking powder
1 tsp. salt
2 eggs, beaten
1 1/4 c. milk
1/4 c. salad oil

Place all dry ingredients in mixing bowl and combine. Add liquids and mix until smooth. Place in a greased 8x12 inch pan and bake in hot 400 degree oven for 30 minutes.

I prefer it when cooked in my 9" Wagner cast iron skillet. If you don't overcook it it will come out fairly moist. I mostly make it to compliment various bean recipes.
I'm going to give that broccoli and cottage cheese variation a try, it sounds good.
