My easy burritos go like this:
Splash of oil
1 onion, chopped
1 tsp cumin
250g tempeh (for the vegan version - use chicken or something otherwise)
1 capsicum, chopped
2 corn cobs, de kernelled
lime juice
3 tomatoes, chopped
1 chilli, chopped
fresh coriander

Put things into a large frypan over high heat in the order they are posted - if it seems to be burning, chuck a little bit of water on it. Also works awesome on the barbecue.

tortillas (I heart homebrand) to serve; sour cream; avocado; a bit of salad if you fancy.

DH does awesome enchiladas, but they are so fiddly.
