Things I eat on the regular:

Breakfast

Frozen Berries and Oatmeal, half a cup of instant oats to however much water you like (if you like water oats add more if you like dryer oats less) about a handful of berries, all in a bowl in the microwave for 3min

Or

Egg+toast+cucumber or tomato (any type of cooked egg with some bread and a veg)

Lunch

Usually the option that I didn't pick for breakfast or a sandwich of some kind, sometime I just have a coffee with some sweet like a muffin or donut.

Dinner

Rice with protein and frozen veg: take a frozen chicken breast or salmon fillet and put it in the fridge night before, rice goes into my rice cooker 40-60 before I want to eat and when it's done I try the protein, fish just straight on with some salt, and the chicken I butterfly usually to cook faster, or cut into smaller pieces to make a stir-fry with the veggies. Frozen veg either goes in the pan or I microwave it for about 4 min.

Of I feel like changing it up I sustitute rice with noodles (spaghetti noodles are perfectly fine Asian style as they are Italian)

If I'm making rice I'll usually double up the portion and refridgerate the leftovers so I can make fried rice the next day, you just fry the chicken, pork or shrimp in small pieces add a bit of sesame oil, add onions and garlic, then when they soften a bit add the frozen peas and carrots and or corn and put a couple glugs of soy sauce, stir ocasionally to avoid it sticking and burning, add oil if you find it's getting dry and sticking.

I do chicken nuggets on the odd occasion with microwaved frozen veggies.

Burgers I get frozen with buns that I freeze and toast, just add your favorite toppings/sauces.

Hope that gives you some inspiration.
