Even though we designed this cook-program to use the pre-cut bags of fresh broccoli and cauliflower that are easily found in nearly every grocery store, this recipe is fairly flexible. If you prefer, you can use either broccoli or cauliflower florets (instead of both), and you can even cut them yourself--just aim for florets that are about 1” big for even cooking. The cheesy sauce we use to make these veggies even more delicious is a riff on classic Mornay sauce, but we’ve swapped out the traditional Gruyere for mild cheddar to make it kid-friendly. Feel free to use sharp cheddar or another strong cheese for a bolder taste, and to thin the sauce with additional milk if you’d like something a bit lighter.
