Some of my personal favorites that are easy to make are noodles mixed with paprika, shrooms and ham(or bacon cut in tiny pieces)
or chicken and tofu with a separate cup of soy sauce mixed with a bit of yoghurt and sesame seasoning and emping and cassave chips on the side. Another is pasta with self-made meatballs, oregano, tomato sauce, fresh basilicum and rasped cheese. Most of these ingredients I buy from this local Italian delicacy shop.
Much better quality and better taste than supermarkets.
I also like to make white rice with a separate sauce of beans, corn, meat and tomatos with separate guacamole and tortilla chips. What I also think is delicious is to boil potatoes in a pot than let them cool off and bake them in a pan combined with a cooked saucage and a salad of lettuce or ruccola, dried tomatoes and a dressing of mayo and yoghurt with a few drops of lemon vinegar. Though that's probably a bit more work.
I also really like to make my own pizza. Just buy a pizza bottom and put your own fresh ingredients on them. Can be anything from ham, pineapple, tuna fish, aubergine, paprika, shrooms etc. Delicious and healthy! I also really like scrambled eggs with bacon though I prefer that in the weekend as a (late) breakfast.
For ideas I also recommend walking into your local delicacy shop. They have really good stuff so just...get creative.
I also recommend to always use fresh ingredients, none of these prefabbed crap that not only tastes like shit but is also not as healthy. I'd advise against skipping meals though(being hungry probably won't do your mood much good), espescially breakfast as that is the most important meal of the day.
