Stuffed Bell Peppers

I have tried these a number of times, but have not been happy enough with the taste to post a reciepe until tonight. Unfortunately... I did not measure anything I put in... so these are guesstaments...
1.5 pounds lean ground beef
Bell Peppers (I did 3 large Green ones)
2 medium zuccini
1/4 Cup worcestershire sauce
1/4 Cup WF Ketchup
Brown beef, Boil peppers in water for about 20 minutes, dice up zuccini.
Drain beef, add zuccini, worcestershire sauce, ketchup and your choice of seasonings, cover and simmer while peppers are boiling. I covered the peppers for about 10 min.
Drain peppers and place in a lightly greased baking dish, add meat mixture, cover with foil, bake at 350 for 30 minutes
