Pour the beans into a medium pan on a medium-high heat, juice and all.
Add ½ a mug of rice and 1 mug of boiling kettle water (300ml).
Season with sea salt and black pepper, stir, and cook uncovered for 12 minutes.
Cover and turn the heat off.
Meanwhile, peel and finely slice the garlic, then cook in a non-stick frying pan on a medium-high heat with 1 tablespoon of olive oil, removing to a plate when lightly golden.
Strip in the rosemary for 1 minute, removing once crispy.
Trim the pork of any sinew, then cut into two chunky pieces and rub all over with pepper.
Cook for 12 minutes, or until just cooked through, turning regularly, while you halve or quarter the cherry tomatoes, finely slice the chillies, season, and mix with ½ a tablespoon each of red wine vinegar and extra virgin olive oil.
Move the pork to a plate, spoon over the BBQ sauce, then bejewel with the crispy garlic and rosemary and leave to rest.
Plate up the rice and beans, with the tomato salad on the side, and serve with the bejewelled pork.
