Roll up and freeze these single-serving burritos and they'll be ready any time - for lunch, supper or even a quick snack!! It's also a good thing to make a big batch of these ,and have quite a few on hand, the family will appreciate it!!
In a large non-stick skillet, heat oil over medium-high heat. Cook chicken, covered, until browned and cooked through, about 12 minutes. Cool slightly and shred. Transfer to a bowl and mix with onion and salsa.
Divide mixture evenly between tortillas. Sprnkle with cheese. Fold in sides, and roll up to enclose filling. Wrap individually in parchment paper and store in a resealable plastic freezer bag to freeze.
To serve, microwave, one at a time, on HIGH until the filling is hot, about 2 minutes from frozen or 1 minute from fresh. Let stand at least 2 minutes before eating. Alternatively, remove parchment paper, wrap in foil, and bake in a 350F oven for abour 20 minutes from frozen or cook unwrapped in a panini press , grill pan, or skillet until tortilla is golden, filling is hot and cheese is melted, about 8 minutes, from fresh.
