Sauté the seafood in a non-stick skillet with as little oil as possible, it will depend on the chorizo sausage some are much drier then others. Sauté until just done and remove from pan but retain the oil. Add the veg when hot and then add the Cajun spice and cumin, stir and sauté until the veg is just soft but with a bit of crispness.  Place on large serving plate with the seafood on top squeeze a ½ lime on top and serve immediately. Not spicy enough for you? Then add more Cajun spice or perhaps throw in a couple of sliced jalapeño peppers.
Warm both sides of the tortillas in a skillet, place in foil and keep warm in oven until service.
Place, sour cream, salsa, guacamole, sliced jalapeño peppers and the shredded cheese in dishes, set it all in the middle of the table and let everyone help themselves
If you’ve got little ones make a separate batch of veg without so much spice.  Make sure you do add some spice and sooner than you know they’ll want to have the regular heat.  Maybe add some of their favourite vegetables as well. The kids will have fun “making their own dinner”.
