Well, I don't know if this would qualify as healthy for you (depends on how you feel about sausage), but this is a quick and easy fave of mine.
Sausage and Peppers in a Pita
1lb italian sausage (I use hot, but mild is fine)
1 medium onion, sliced into half-rings
1 large pepper, sliced into strips (I like red peppers, but green is fine)
1 tbsp olive oil
1 can tomato paste
1 tsp fennel seeds
1 tsp basil
1/2 tsp oregano (or use 1 tsp italian seasoning instead of basil and oregano)
saute the sausage in olive oil until cooked through, remove from pan and saute peppers and onions until they begin to soften. When the sausage is cooled a bit, cut it into bite sized pieces and return to pan. Add the seasonings, tomato paste and 1 can of water, stir to mix it all up, then cover the pan and cook until the veggies are soft, the sauce has thickened up and the flavours have blended nicely (I give it about 15 minutes). Spoon out into a large pita bread, roll up and serve. I wrap the rolled-up pita in tin foil so it doesn't drip, and we can eat them as finger food (sorta
This in incredibly tasty for how easy it is to make, it's my fall back quick recipe, but like I said, it depends on how healthy you feel sausages are. I buy mine from a local italian shop where the meat is butchered on site and I know exactly what's in them, so I feel ok about eating them once in a while.
If you have a bit more time, there's nothing like a big pot of lentil soup. For nearly instant lentil soup you can use canned, but lentils cook so quickly, you can still put together a pot of soup in under 45 minutes. I use my crock pot a lot when I want to put together frugal meals, too. Not quick, in that it takes 8-10 hours, but I can spend a few minutes in the morning putting dinner together, and not worry about it again. Especially great for me because I work evenings some nights a week, and I'm making dinner, but won't be home to eat it until after 10pm. There are as many different lentil soup recipes as there are cooks, I'm sure, I have more than one myself. I won't bother posting any of them.
Pasta salads are another great quick option, use whole wheat pasta and canned or frozen beans, or tuna, with fresh veggies and a quick vinagrette.
I blog about meal planning (yeah, I think about food all the time, maybe that's why I'm permanently trying to lose 40lbs
), here's a link to a quinoa greek salad
recipe I posted a while back, rather than typing it up again.
