Stuffed Zucchini

My mother-in-law gave us the biggest zucchini I have ever seen this weekend, along with some homegrown tomatoes. Picture a normal green zucchini, but about a foot long and twice as thick as a Subway sandwich. She told me to stuff it with onion, bacon, tomato and cheese, so I change it up a bit. I cut it in half lengthwise and scooped out the junk in the middle, then rubbed some olive oil on the inside and sprinkled salt, pepper and basil over. Next I cut up 1/2 a red onion, diced 4 tomatoes, and placed that in. I baked it on about 180-200C for about an hour. When it was cooked I shut the oven off and topped with some tasty cheese, although I think mozzarella would also do. I will attempt to take a pic of the leftover one tomorrow, although as you know, I'm very slack on the photos.
