Preheat oven to 180°C.
Heat oil in a frypan over medium heat, add mince and spices. Cook stirring till browned. (You can cook this part in the Thermomix but we decided to go old school and chunky for this recipe!)
To char the corn, place cob over a flame, turn until charred evenly all over. Cut kernels off. Add to mince along with the salsa and beans.
To assemble lasagna, in a lasagna dish, layer meat sauce, béchamel and lasagna sheets. Repeat layers finishing with cheese sauce and topped with grated cheese.
Bake for 35-40 minutes. Until browned and cooked through.
Combine avocado and lime juice.
Serve with avocado and sour cream and garnishes. (A lime cheek never goes astray)
