First off divide the onion and the capsicum in to 3 pieces and place them out on the bottom of the slow cooker. Add no more than 1cm of water to the slow cooker.
Next I prepare my roast in my sink. I make sure my sink is clean before I start.
After the roast is taken out of the packaging I rinse it off in cold water.
I rub 2 heaped teaspoons of crushed garlic in to the roast, while evenly spreading the garlic all over the roast.
Then sprinkle vegeta, salt, pepper, rosemary all over the roast. Rub it all in to the roast with the garlic.
Add the roast in to the slow cooker placing it on top of the onion and capsicum. Lightly splash lemon juice just over the top of the roast.
Optional vegetables. You don't have to but I always add in what potatoes my family will eat. I just peel them and add them in whole. I also add in carrots, again peeling them and cutting off their ends, and the same with the sweet potato. I sprinkle only vegeta over the vegetables. You can serve additional vegetables of your own choice with this roast.
Put the lid on. Turn the slow cooker on low and leave for 7+ hours depending how cooked you wish it to be. Or 5-6 hours on high.
