Using a large skillet brown the sausage and cook till done (about 8 minutes). Break into small pieces.

Combine eggs and milk and whisk together until blended. Add to skillet with sausage. Cook until the eggs are set (about 5-7 minutes).

Add in salsa and cheese to the sausage and egg mixture. Cook for another 5-7minutes or until cheese is melted and eggs are completely cooked.

After it is finished cooking let the mixture cool slightly.

Lay tortillas flat then in the center add ⅓ cup of the mixture and roll up.

Tips:

To freeze, wrap each burrito in plastic wrap and then place all into a freezer bag(s).

To reheat, take burritos out and put in the refrigerator the night before. Take burrito out of the freezer bag and plastic wrap. Place in the microwave for 2½ minutes. When you warm up in the microwave place a coffee mug full of water in as well. The steam from the water as it cooks keeps the edges from getting hard.
These can also be warmed up in the toaster oven or a panini press. Be careful of some of the juices that might come out when biting into it.
