Ok- exercise was fabulous, big tick 3k run, 1k row, 12k cycle and 5 weights circuit (4x15 reps of each)

Food, big thumbs down DD didn't like her lunch so i ended up eating two bowls of pasta (i made double for her dinner as well), on top of my well intended velish pumpkin soup, and then i added in 2 slices of pana di cassa bread with butter... How can i salvage this? I was thinking of having a tuna salad (tuna, lettuce, corn, tomato, cucumber) for dinner instead of the family dinner. I am breastfeeding, so i am giving myself 500 additional calories, but i think all this pasta was a bit over the top!
