Lunch ideas on the go

Homemade soup in a flask. Satisfying and a whole meal in one, (depending what you put in it).
If you don't like hot soup at this time of year - try a nice chilled soup: gazpacho or vichyssoise. Cold soups are massively underrated in my opinion!

I usually take a picture of low carb protein shakes, beef jerkey, grilled chicken I premake on Sundays, taco meat on a salad, almonds, or cans of tuna
