Put the chicken breast to cook,add salt and chicken flavor bouillon

Bring to boil the chiles guajillo and tomatoes untill tender and set aside

When chicken breast is cooked take it out and let cool of and when cooled off shred it

With the same water that you cooked the chicken breast add to the blender (not all of it)about 3 or 4 cup,add the chile guajillos,add the tomatoes and the can of tomato sauce and a bit of all purpose flour (just so its not so waterylike) then blend

Add a lil bit of corn oil to a skillet and the the chile sauce with a colander turn off when hot

In a small skillet heat corn oil and fry tortilla until golden brown but still pliable,about 10 sec per side,transfer to paper towels to drain

Put tortilla on work surface,divide the shredded chicken evenly among the tortillas and roll like a cigar

On the rolled tortilla drizzle sour cream add the chile sauce

Top with cheese and lettuce and serve immediately

I like eating them aside with boiled eggs
