Mexican
Warm the beans with the cumin and chili powder, mashing lightly, and reheat the rice and meat if needed.
Warm each tortilla in a dry pan until soft and pliable.
Spread rice down the center of a tortilla, then layer beans and meat on top.
Add cheese, salsa, sour cream and avocado, finishing with a squeeze of lime and coriander.
Fold in the sides of the tortilla, then roll it up tightly into a sealed parcel.
For a crisp finish, toast the seam-side down in a hot dry pan until golden.
Cut in half and serve.
