I just came up with an easy and tasty recipe. Measurements are far from exact.
What you will need:
Aprox 1 lb stew meat
1 packet Mrs. Grass onion soup mix (Or a packet of whatever onion soup mix you prefer. I can only attest to the tastiness of this particular brand though)
1 packet of random mashed potato flakes. (I used one of the "fully loaded" flavors this time. I plan on experimenting with different varieties)
Some sort of large pan
1. Brown the meat. Leave all the grease and juice (or don't if you are a health nut. Use more water in the next step)
2. Mix in onion soup powder. Add enough water so the meat is covered entirely.
3. Let onion soup simmer with the meat until the onion pieces are tender
4. Turn off heat and stir in the potatoes. Add enough milk so the potatoes are a creamy consistency. This is the part where butter is optional. I added quite a bit of butter here but more milk will likely work just as well.
