If making it from scratch, make your simple salsa.
Gently simmer the sausages for 5 minutes to soften the casing and reduce snap.
Get the grill nice and hot. Throw the sausage links on the grill for 5-6 minutes on each side. You want them with grill marks, but still juicy.
Steaming the tortillas first makes them taste fresher. Wrap your corn tortillas in a wet paper towel and steam them for a half-minute in the microwave.
Warm a pan on medium-heat, wipe it with vegetable oil, and toss the tortillas in there for about a minute. Flip and repeat.
Remove the sausages from the grill and let rest a minute. Meanwhile, you can use this time to chiffonade the lettuce and slice the jalapeño.
Slice the sausage then layer your tacos with all ingredients. Add a spritz of lime. Serve.
