I don't like squash, so I substituted the squash with Knorr's Buffalo Chicken side dish.
I made half of what the recipe called for, and one package of Knorrs was perfect for that amount. Just be sure to add a little extra chicken broth so your stew doesn't dry out, and add the rice about 7 minutes before you're done cooking.
Just a note a day later....loved the meal. If you like it spicy this one's for you!
