I typically use them as mix-ins.
Frozen chopped spinach in soups, pasta sauce, pizza sauce. I put it in everything!
Mixed vegetables in soup, chicken pot pie.

For very quick fresh veg, pierce a bag of fresh green beans, microwave for 5 min, add a bit of olive oil or butter and salt.
Or roast asparagus for 5-7 min.

I need help with making frozen vegetables more appealing. Do you have any ideas on how to prepare/cook them to make them taste better?
