Thai Red Curry Tofu and Veggies

I had such high hopes for this recipes and was pretty disappointed with the results. I followed the recipe very closely, only making one modification. The recipe called for 1 1/2 packages of tofu, and I just used one package. I cooked the vegetables for 7 hours on low. The results were very watery, and the vegetables were over cooked. If I were to make this one again, I would only add one cup of water (instead of two), and I would cook it for four hours on low. Also, the recipe says to add the broccoli about 20 minutes before you are ready to serve. After 20 minutes, the broccoli was no where close to tender.
