Cut your butternut squash in half length ways, on a lined and well oiled and rimed cookie sheet bake at 375 for 60-90 minutes until fork tender.
Let squash cool just a bit until you can handle it and turn your oven up to 475. Once squash is touchable scoop out the meat leaving about a inch all around the squash, this will be your bowl.
In a large bowl mix squash meat, salt, pepper, mustard, garlic powder, and egg. Mix well.
Add in the ham, chicken, and 6oz of cheese mix well then fill your squash bowls
Top with swiss cheese and put back in oven for about 15min until swiss is melted and browned
Slice to serve, remember butternut skin is edible but you can also peal it off as you eat if you don't like the texture
