BROCCOLI:

  • We have to use broccoli, as it will give a crunchy texture and fiber content. As a replacement, you can use asparagus pieces, brussels sprouts, or green beans.

ZUCCHINI:

  • Use zucchini, which will provide softness and moisture content. We can substitute it with chayote, eggplant, or yellow squash.

BELL PEPPERS:

  • These peppers will deliver a color and a mildly sweet taste to this veggie casserole. As an alternative, you can use celery, poblano peppers, or green chilies.

MUSHROOMS:
