Ah, I see. Well, there is nothing wrong with those kits. They work and make decent beer.
What I'm thinking of are different kits, like Brewer's Best kits, or those from some of the online homebrew stores (like austinhomebrew.com) that come with some grains as well.
Here's an example of one of my recipes made with some grains:
Dead Guy Clone
1 pound Cara-Munich
1 pound Munich
1/2 pound crystal 40L
Steep grains in a bag at 155 degrees for 30 minutes. Sparge with 1/2 gallon 170 degree water. Allow grains to drip into pot, but don't squeeze. Discard grains. Bring to a boil and add:
4lbs Alexanders Pale LME
4LBS LDME
(I substituted all XLDME)
Hops:
1 oz perle 60 mins
1/4 oz perle 30 minutes
1/4 oz perle 5 mins
1/4 oz saaz 5 mins.
In that case, the grains will give body, color, flavor, and a decent head while the extract provides the fermentables.
You may be very happy with the kit you have, though, so don't worry about it right now. Just keep in mind some options for the next batch.
