I found this recipe and tweaked it to my own preferences. I also found that I needed to bake the squash longer for it to be soft enough, though I may have not hollowed it out enough in the beginning.
Luckily I had an extra squash because in the hollowing out process I got a little over ambitious with the first one and put a hole in the bottom. I was more gentle with the next two.
Since all breakfast is better with bacon I fried up a few pieces to crumble inside and then sauteed the onions in the bacon fat.
After stuffing the squash with the bacon and onion mixture I topped them with eggs. I scrambled my egg and left LJ's whole for a comparison.
You can see I overfilled each squash so the egg came out over the top as it cooked
If I were to do this again, I would also add a little cheese with the bacon and onions and scramble all the eggs. It would also be helpful to have a grapefruit spoon to take out the sides of the squash. Overall it was pretty good and a nice way to get some vegetables in for breakfast.
