    • It reminded me of a broccoli, rice and cheese recipe that I make, in taste only. I actually thought it would be really good with rice added. I knew it was good when my husband went back for seconds.


  1. Zucchini is one of those things. You either love it or hate it. We here love it! Try slicing it thin and frying in olive oil. Then pour it all over some good spaghetti or linguini. A true feast for the palate.


  2. Nice! We have been eating quite a bit of zucchini lately. Our favorite, although not fancy, is simply taking some sliced, well-seasoned zucchini and placing it on our Korean BBQ grill.

    After several minutes on each side, you see the lovely char marks. These go perfectly with thinly sliced brisket or hotpot beef.

    • As I was eating it Barb I was thinking of how good it would be to throw in some chicken and rice for a complete meal, although it could be a complete meal just like this too. We enjoyed it as a side dish and my hubby went back for seconds!
