I got this reciepe from a friend over 20 years ago and have made it for my kids and now grandkids,it's a great way to get them to eat their vegetables.You can use either Spinach or Broccoli in this...Hope it's as big a hit in your family as it has been in mine..Enjoy !!
Open the boxes of Spinach OR Broccoli and place in colander overnight so that they are completely thawed and squeeze out the juices with your hands or by pressing down with wooden spoon.DO NOT COOK.
Place Thawed Spinach OR Broccoli into a large mixing bowl,set aside.
In a medium sized bowl,beat the 3 Eggs,add the milk,then all the dry ingredients as well as the onions
Pour over the Spinach OR Broccoli,then begin to mix with hands or wooden spoon,slowly adding the cheese to incorporate it into the mixture
Heat oven to 350 degrees.Place 1/4 Cup of butter into a 13x9 inch baking dish and place into the oven and melt,watching carefully so it doesn't burn.Remove pan from oven.
Now pour mixture into pan over the top of the melted butter.Do not mix ,just spread evenly with a wooden spoon
Bake at 350 degrees for 1 hour or until edges begin to brown and there's a nice golden brown top,remove from oven and cool for 30 minutes and then cut into squares.Cut into Brownie size squares if using as a side dish or smaller squares if using for appetizers
You can freeze any leftovers,as these freeze well for future use.Or store in fridge for up to 3 days
