Broccoli Cauliflower Gratin

Besides the delicious taste, one thing I love about Broccoli Cauliflower Gratin is it can be made into different dishes. You can make it as the name says and use both broccoli and cauliflower. Not a cauliflower fan? No problem! Leave out the cauliflower and make a broccoli gratin. Not in the mood for broccoli? Just use cauliflower for a cauliflower gratin. Want to up the healthiness? Add carrots and make it more of a California mixed vegetable gratin.

Cooking Tips

Save time by using vegetables that are already washed and cut up for you. For this recipe, you need roughly six cups of vegetables. That six cups can be of just one vegetable or combination of two or three.

If you want to take broccoli cauliflower gratin to the next level, substitute the 1 teaspoon of salt for a tablespoon of chicharron salt. You can thank me later! (Warning: chicharron salt does contain pork.)
