Disappointed by Martha?!

I have been looking for a vegetarian-friendly stuffed peppers recipe for a while now. Yesterday on the Martha show, she made Greek stuffed peppers that sounded so good. I went to the market and was really looking forward to surprising S with dinner last last. Well, it turned out to be a bust. You use dry couscous (which didn't seem to cook at the way through) and they were very bland. You couldn't taste the stuffing beforehand since it had raw couscous. Next time I think I will either cook the couscous to season it up better or try some rice or other grain...and more seasoning.
Here's the recipe to try it for yourself:

Ingredients
Serves 4
4 large bell peppers
1 can (15 ounces) cannellini beans, rinsed and drained
1 cup crumbled feta (4 ounces)
1/2 cup couscous
4 scallions, white and green parts separated, thinly sliced
1 garlic clove, minced
1 teaspoon dried oregano
Coarse salt and ground pepper
Lemon wedges, for serving

Directions
Slice a very thin layer from the base of each bell pepper so they sit flat. Slice off tops just below stem. Discard stems; chop tops, and place in a medium bowl. Remove ribs and seeds from peppers.
To bowl, add beans, feta, couscous, scallion whites, garlic, and oregano. Season with salt and pepper, and toss to combine. Stuff peppers with bean mixture.
Preheat oven to 350 degrees. Use a 5-quart Dutch oven or ovenproof pot with a tight-fitting lid; add 1 cup water. Cover; bake until peppers are tender, about 1 hour.
