Lots of juicy details missing there. Type of roll, size (cross-section) of roll, number of pieces. Could be one of those huge jumbo rolls that you can't fit into your mouth with 8 pieces each with tempura and mayo, could be a skinny cucumber roll with 6 pieces. My major meal of the day is lunch (just how I like it, and how it works out with my lifestyle), and my "usual" sushi lunch would be 6 pieces plain california roll, 3+3 pieces tuna/salmon nigiri, and 3+3 pieces tuna/salmon sashimi. Totals out almost 800 calories (quite a bit, most my lunches are 700-750) and blows my daily protein targets out of the water. Also filling as fuck. When I was working on weight loss and caloric deficit, this would be a splurge, because it's pushing 50% of my daily calories, but now that I'm on maintenance and some low level body building, it's a more regular occurrence.
