Lettuce Boats with Mexican-Style Minced Meat

• Heat a drizzle of olive oil in a frying pan over medium-high heat.
• Add the onion, bell pepper, BBQ spice rub and Mexican-style spices and fry for 2 - 3 minutes.
• Add the tomato paste and minced beef, then fry for 4 - 6 minutes, or until the meat is cooked through.
• Add the grated cheese in the last minute, stir everything together and let the cheese melt.

• Finely dice the tomato and cut the lime into wedges.
• In a small bowl, mix the tomato with the rest of the onion and the juice of 1 lime wedge each. Season with salt and pepper to taste.
• Pull 4 lettuce leaves per person off the little gem (see Tip).

Tip: you can also put two leaves together to make the lettuce tacos bigger: then you'll need 8 leaves per person.
