We went to a Farmers' Market at Old Colorado City recently and I enjoyed the experience. I picked up these round summer squash which was called "Geode", it was light green and tasted like zucchini. The round shape makes it suitable to sandwich with your burger. I also picked up some sweet yellow onions and yellow carrots. The easiest and tasty way to enjoy these vegetable is by grilling them or roasting it in the oven. I took out some chicken tenders and seasoned it with some extra virgin olive oil, salt, rosemary, peppers, and sage. I also added some yellow and red bell peppers. Thus far, I have only seen "Geode" selling in the farmers' market here. From my experience, don't pick the big one as it will have bigger seeds.
Cut all the produce and season it with extra virgin olive oil, salt, peppers and spices of your choice. (you can use Italian seasonings, dried thyme, paprika, garlic powder, etc) Then, roast in preheated 450'F oven for 15-20 minutes or until soft and slightly brown.
I lined my baking pan with aluminum foil for easy clean up. This certainly was an quick and easy dinner with little washing.
