In a large saucepan, heat oil/butter. Soften and slightly brown onion.
Add rice. Stir and brown slightly over high heat.
Add canned tomatoes (with liquid), canned mushrooms (with liquid), meat, and about 2 cups water.
Add Vegeta powder. Stir. Cover and bring to simmer.
Simmer on medium-low heat, covered, stirring occasionally and adding extra water as necessary.
Cook until rice is tender, about 20 minutes.
Season with parsley and extra salt and pepper as needed.
Notes:
Use salt and pepper if you do not have Vegeta.
Add other canned vegetables if desired; omit mushrooms if desired.
Add a can of corned beef about 5 minutes before the rice is cooked.
Instead of the canned tomatoes, add a can of tomato sauce.
If you have any leftover gravy, add it.
If you want to serve this as a side dish to meat, omit the meat in the rice.
Serve this with butternut squash, as I have in the photo above.
