For easy chicken and dumplings on a busy day, prepare the onion and measure the seasonings ahead of time.
You can use frozen peas and carrots or your favorite mixed vegetables. Make sure frozen vegetables are thawed before adding them so they do not significantly lower the temperature inside the slow cooker.
For a chicken and biscuits variation with larger dumplings, cut the flattened biscuits into slightly bigger pieces, allowing additional cooking time when necessary.
Serve the finished dish on its own or pair it with a crisp green salad, steamed green beans, or roasted vegetables.
