How many calories in a salmon avocado roll?

In my recipe for one tin wild sockeye salmon (I use Ocean's):

rinse salmon in tin in cold water to remove excess fish oil (80 calories per 1/4 cup 1 tin = 1 cup so 320 calories total)

1 celery large stalk chopped 2 calories

1 green onion chopped 10 calories

1 tablespoon Kraft Mayo 90 calories

1/3 cup rinsed (thawed) frozen peas 35 calories

The total calories is 457 calories for the whole salmon tin which makes approx 2 - 3 cups salmon which equals 6 - 9 portions per tin depending on how much you put in your wrap.

2 small romaine lettuce leaves (inner stalk) 2 calories

I only use about 1/3 cup of salmon in my wrap

Olafson Regular white wrap (I get bulk from Costco) per wrap is 140 calories.

Breaks down like this

Salmon mix 457 calories divided by 6 portions = 76.17 calories

2 small romain leaves = 2.00 calories

1 regular white wrap = 140.00 Calories

Total Calories = 218.17 calories per wrap
