SWEET POTATO-PUMPKIN GRATIN

• What you need is some sweet potatoes, pumpkin (golden nugget or butternut would be excellent), some onions, garlic, rosemary, thyme, red capsicums, and some cheese( either some feta or gouda-i like this two and they suit the dish)
• cut them all large, mix everything up with some olive oil, add seasonings as simple as salt and pepper but don't over do it because of the cheese. Add chunks of cheese to the dish and gratinate at about 180-200 degrees for 12-15 minutes depending on the color you wanna have.
• Great summer dish and very simple to make.
