Skillet Meat Loaves with Mushroom & Onion Gravy

I must be in a good mood because I always thought to keep this recipe as one of my "family secrets". LOL But it's too yummy not to share! Enjoy!

Ingredients for meat loaves:
1 1/2 lbs lean ground beef
1 egg
1 tsp rubbed sage
1 T Worcestershire sauce
1 T dijon mustard
A handful or 2 of bread crumbs
Salt & pepper
EVOO

1. In a large bowl, mix all ingredients above, except EVOO, just until well-incorporated. Do not over-mix. Form into 6 oval "loaves", about 1" thick.
2. In a large skillet, 1 turn of the pan of EVOO over med-high heat, cook 3 meat loaves at a time. (Don't crowd the pan!) Several minutes on each side should have them well-browned & just cooked through.
3. Set aside and cover with foil to keep warm. Cook remaining 3 loaves.

Ingredients for gravy:
1 onion, sliced
About 2 C sliced mushrooms - crimini or baby bellas are great!
1 T flour
1 C beef stock
1/4 C half 'n' half or heavy cream
Salt & pepper

4. As meat loaves are cooking, prep onions & mushrooms. Set last 3 loaves aside & add about 1 T EVOO & onions to the hot pan. Let them carmelize then add mushrooms, cover with foil & "nest" another skillet into it to smother for about 5 minutes.
5. Add flour, toss to distribute & cook another minute then stir in beef stock. Bring to a simmer & let thicken.
6. Stir in cream, salt & pepper if needed. Serve gravy over meat loaves.
