what are some quick and easy lunches?

this week i have been eating within my calories (im under a tiny bit), sugar, protein( i eat more than MFP suggests for protein) so im not over any intakes. BUT for lunch i have been eating Amy's gluten free mac n cheese. it has 16g of protein, 16g fat, 400 calories 6g of sugar, 86 carbs 640g sodium (ouch) . Along with a banana / apple, sometimes green beans a yogurt and one day I had a sandwich too. I was on a budget this week so i had to go cheap. Tomorrow my lunch will not be the same as it has been all week. i need more lunch suggestions, i don't like salad, i wish i did. I know my lunches this week were not THAT healthy. According to MFP i need to be eating more fats, calories, ( only a small amount) and more carbs. the only "unhealthy" meal i eat is lunch. for breakfast and dinner i do good, but lunch is my weakness.. i think maybe that is the reason i got sick? because im working out and not eating enough good food? like i said im low on carbs, fats and barley calories. no rude answers, i am trying here but i need help! this is not an escuse but i did lose both my grandpartns in the last month. I work with my mom so it has been a really rough week ( my grandma passed last weekend) so im really stressed and now im sick, to make things worse my boyfriend got put onto 2nd shift so everything is just different.. i just know i need to be eating better now that my life is getting back to" normal" again and i got paid lol i should mention though that i am always hungry. no matter how much i eat or how healthy it is i will be hungry within1-2 hours, it has always been like that and now that im working out im even hungrier. so small meals are great but hard for me, i can't be eating all day at work.
