Food and recipes

I’ve never been a chef, so sorry if this is a stupid question, but I’ve heard adding oils (such as olive oil, canola oil, etc) into foods and drinks adds a lot of calories without affecting the taste too much. But, I tried adding some olive oil (around a tablespoon) to my protein shake, and it would not mix, looked gross, tasted awful, and ruined my protein shake! How are people adding extra oil to foods and drinks without it being so noticeably disgusting?

Thank you, I’ll try that out! I eat a lot of pasta, so I’ll try to really oil that up.
