Zucchini peeled, cut into fairly large cubes. To reduce the time for further baking, you can boil these pieces 5-10 minutes or fry a little. I didn't it.
Add the zucchini to the oatmeal.
Remove the skin from the pepper. To do this, bake the peppers on a grill or open fire to tan, put in a bag, tie tightly and leave for 10-15 minutes (I baked the peppers in the oven under the grill). When the pepper cools down, the skin is easily removed. Cut the pepper.
Onions cut and fry in vegetable oil until transparent.
To prepare the filling – mix the cream, grated cheese, eggs, add your favorite spices (I prefer salt and pepper).
Mix the zucchini, onion, bell pepper, pour the cream mixture.
Put in form. I didn't grease it because I used silicone.
Bake at 180-200 with 1 hour. If the zucchini is pretreated (see paragraph 1), the time can be reduced to 30 minutes.
