Yesterday vegan all day, and logged on food and nutrition tracker:

Breakfast: Wholemeal toast and marmite, Miso soup in a cup
Lunch: Cabbage, potato and caraway soup, with brown bread
Dinner: Cajun brown rice and blackeye-beans, Steamed spring greens, Pumpkin and split pea patty

Calories: 1364 - intentionally less than I need due to portion control for weight loss
Protein: 54g - about 8g more than I need (46g)

In case there is still any doubt concerning protein sources on a plant-based diet, I'm just illustrating how easy it is to get protein. Looking at the breakdown, two slices of wholemeal bread gave me 10g, the blackeye beans another 10g, and the split pea and pumpkin patty 13g, the rice 5g, the soup 12g and miscellaneous extras from other odds and sods like the miso and yeast extract.

If my intentionally reduced portion sizes had been large enough to bump me up to 2000kcal, which is the amount generally advised for adult women, then my protein intake would reflect that and be more like 77g which is considerably more than I actually need.

I hope that all makes sense!
