Beefy Comfort in a Bowl

... Sounds a lot better than SoR - Slop on Rice.
Basically this is just simple beef gravy on rice with peas, but it is oh so good and comforting.

2 pounds lean ground beef
1 medium onion, chopped
1 tbs garlic, chopped
1 tbs dried parsley
1/2 tsp dried thyme
1/2 tsp dried mustard powder
3 tbs worcestershire sauce
1 packet Onion Soup & Dip Mix (check that it is dairy and gluten free)
1 quart beef broth
2 tbs corn starch
seasoning salt
black pepper

cooked white rice
cooked green peas

Brown the ground beef.
Drain off any excess fat.
Add the onions, garlic, parsley, thyme, seasoning salt, and black pepper.
Saute until the onions are tender.
Add the beef broth, worcestershire sauce, dried mustard powder, and onion soup mix.
Bring to a boil then reduce heat to simmer and cover.
Cook about 15 minutes.
Mix the corn starch with a small amount of water.
Bring the pot back up to a boil.
Add the corn starch and boil for a minute to thicken.
Taste and adjust seasonings as needed.
Serve on a bed of white rice and topped with green peas.
