If I am eating a salad eg. May I say one Bracha for all of the fruit items, or should I say them individually? Also if I have mixed it all with olive oil and cheese, should I just say bidvaro? Sorry, trying to return to Teshuvah, but never had the opportunity to learn this.

ב"ה Shalom When you are eating a fruit salad, one Bracha for fruit is sufficient for the all fruit in front of you. If your fruit salad also contains fruits whose Bracha is "Borei pri Ha'adama ", such as strawberries or pineapple, if the fruits whose Bracha is "Borei Pri Ha'etz" is the majority of the salad, then also you say ONLY "Borei Pri Ha'etz", because that is the main part of the salad and the pineapple is only secondary. (See Shulchan Aruch Orach Chaim 206:5, 212:1) If you mixed in cheese and olive oil into you fruit salad, the cheese again is only secondary, therefore no Bracha is recited for it only for the fruit. In all scenarios, one does not recite a blessing for oil on its own ( See Shulchan Aruch Oracvh Chaim 202:4, Shut Yabia Omer Orach Chaim Vol. VI, 48:6) No need to apologize for asking. Our Rabbi have said in Pirkei Avot 2:5 that a shy person (who doesn't ask) doesn't learn things. Besides, your question can be asked even by somebody who had a religious upbringing. All the best and keep on asking.
