Can I Eat Solid Food 4 Days After Tooth Extraction?

Got my lower left tooth taken out 4 days ago. Went for a check up and the dentist says its healing good and gave me a syringe to clean after I eat as well. Can I start eating solid food like some McDonalds now. I DON'T want to get dry socket but the dentist said Im clear of that(shouldve felt it sooner he says). Can I eat regular food now and am I still at risk for dry socket?
