Never tried brown rice in the crock pot, but you can do it in the microwave: use a microwave safe covered casserole dish; add 2 cups water, 1 cup rice, 1 tsp salt, and 1 tsp vegetable oil. Cover and cook on high for 5-6 minutes (until water boils. Remove from oven and let sit 10 minutes; return to microwave and cook and additional 3-5 minutes. Let stand 5 minutes. Fluff and serve. If the rice isn't fully done, you can zap it a minute more at a time...
As for the crockpot recipies, http://www.dietsinreview.com/recipes/Crock-Pot-Pizza/ I made a version of the crock pot pizza and my whole family loved it. I used a little more cheese (I know that's not very weight-watcher-y of me!), and "small shells" macaroni. You can always cook a whole bunch of ground meat with onions at once and keep it in the freezer for crock pot recipes like this one. I tried the pineapple chicken, too. It was all right, but not great. Another recipe I like from the crock is to get a pork shoulder roast, pour on 1/2 a bottle of BBQ sauce, and simmer on low all day, then shred it. You could use salsa instead of BBQ sauce and make tacos. It'd probably work with chicken, too (since you don't want pork), if there was enough moisture to keep the chicken from drying out. Parents' magazine has a crock pot lasagna recipe that's OK, too (but I prefer the regular baked kind); someone reproduced it here: http://sheilasrecipes.blogspot.com/2007/12/veggie-lasagna...
