I bought a section of butternut squash, peeled it, put in my Tupperware steamer and microwaved it for 3 minutes. After it has cooled, cut into bite size cubes. The squash should be undercooked because you will be caramelizing it with the onions.

*Eliminate the butter and double the olive oil for Vegan preparation.
