Question about logging daily intake

 I have been trying to keep up with my protein by using the daily nutrition tracker.. My question is last night I made homemade vegetable beef soup and with all the mixture of ingredients I use, how do I track something like that to figure out my protein? 

 I use an online tracker called sparkpeople.com.  It allows me to enter a recipe and it figures everything out.  Give it a try or search online for another.
