In a skillet over medium heat, cook the chopped bacon to your desired preference.

Remove the bacon to a paper towel-lined plate and set aside.

Add the diced onions and cauliflower to the hot skillet and cook for 4-5 minutes, until onions are translucent and cauliflower browned.

Stir occasionally.

In a medium bowl, whisk together cornstarch and milk.

Stir the milk mixture into the cauliflower.

Heat for 2 minutes, stirring occasionally.

Sprinkle both cheeses and the bacon onto the cauliflower.

Cover in tinfoil and place in the campfire coals for 8-10 minutes or put into a 350 degree F oven and bake for 8-10 minutes.

Bake until cheeses are melted.

Serve warm.
