Combine the OHCo. Cajun Spice with 2 tablespoons of either OHCo. Chilli Savory oil or Irish Garden Herb oil.
Place the roast in a large roasting pan, fat side up.Make 6 to 12 deep cuts into the meat to form pockets down to a depth of 2cm from the bottom.
Fill these with the above seasoned vegetable mix keeping about 1 tablespoon of the vegetables to rub over the top of the roast.
Slow cook, uncovered at 150°C for 3 hours for medium or slightly less for rare.
Lightly season with OHCo. Herb Sea salt, drizzle with juices from the pan & serve immediately.
