How did you deal with a plateau?

Hello, I’m a 25m 5’10, over the past 6 months I’ve lost nearly 30 pounds. I still want to lose about 7-10 pounds for my goal weight, however I’ve noticed that I’ve seemed to hit a plateau. For context, I work a very physical job, I’m on my feet and lifting for 9-10 hours a day. I probably consume no more than 2300 calories a day , most of which is lean protein besides breakfast (protein bar and banana). For dinner I usually consume 2 chicken breasts or salmon, with cauliflower. The only drinks that I consume are water, and i’ll have maybe one gatorade a day for the sugar and electrolytes. On your journeys, how did you deal with a plateau, and what advice would you give me to lose these final 7-10 pounds? Thanks
