soybeans

Hi all, I have found I LOVE edamame so I had my dad bring me some soybeans (he's a farmer) but they were soybeans he had harvested (so they were not grean & In pods). I put some olive oil and salt on them and baked in oven.....they dont taste like the roasted edamame I bought in store but are still pretty good. my question is how do I know the calorie content? Any suggestions?
