Is this a healthy Lunch & Dinner?

Due to a recent health scare I am changing my diet, this requires me to lose weight for my blood pressure and reducing sodium.

I am a person who can eat the same thing for weeks then make variable changes.

Lunch- Handful Snow Peas (raw) Handful Carrots (raw) 1 small Cucumber, handful no salt added almonds and a teaspoon of ceasar dressing.

Snack- No Sugar Jello + Small Piece Dark Chocolate

Dinner- Salmon/Chicken (portion sizr) 1/2 cup rice, steamed veggies in water and a full orange.

I only drink water, hot tea (no sugar) and coconut water (going forward)

i Havent gotten what to do for breakfast yet but it is important I reduce sodium and sweets and bad carbs and bad fats. What can I add or change, I only eat chicken and fish, rarely do pork or beef, but I need to make this change now so I already started today. Any advice would be helpful.
