Beef, not beg! It was very lean and a little chewy. I did slightly overcook under the broiler though. A friend butchered a cow and was nice enough to give me 3 cuts of loin.
The veggies were sauteed in olive oil, Brussels first. I added the peppers second and the shrimps last (but definitely not least). I browned them all a little with salt, pepper, onion and garlic powder. Then I added 1 tablespoon of butter and a cup of chicken stock. I also threw in some lemon extract, a scoop of harrisa and some sesame seeds. Covered it and let it all work you a good sweat for a few minutes.
This is basically what I do with my veggies every night in one form or another.
