Heat oven to 375 and preheat a skillet to medium heat with olive oil. Melt the butter in the microwave with the water. Sautee onions, garlic, and broccoli in the olive oil for 5 - 10 minutes until softened.

Mix the Jiffy, half and half, water, cottage cheese, eggs, salt, cheddar and melted butter together in a big bowl—you can leave out some of the cheddar to sprinkle on the top later, or you can just grate more cheddar for the top.

Add the broccoli/onion combo to the batter and mix that up, and then pour it into your baking dish—9x13 or equivalent. Bake for 30 - 40 minutes until golden on top and a toothpick or fork inserted in the center comes out clean. Let cool for 5 - 10 minutes before slicing and serving. May be made a day or two in advance and kept covered.
