GAnother person who avidly studies the supermarket fliers.
This time of year fresh produce is cheap and plentiful so I buy enough for now and flash freeze for later.
Here are some of the dishes I've made during the hot and muggy days we are having currently:

Made it last night minus the jicama (replaced it with an ear of corn that I sliced straight through making mini ears of corn) and added more zucchini as it's really coming into it's own right now and removed the 'shrooms since one of us doesn't like them. Had no more Chinese rice wine so used white vermouth instead. You might want to ignore the instructions to add salt during the marinating portion since I think it would make the final dish too salty what with the soy sauce and salt used later in the recipe. Oh and if you've no cashews on hand peanuts will work just as well. Nut allergy? Just don't use any; dish will still taste fine. Think it took about 30 minutes of active cooking to bring to table.
This is the time of year to make a big ol' pot of ratatouille on my end. The main ingredients are nice and fresh. I serve it as a side dish, a main over rice or pasta, in an omelet or w/ grilled meat.

This dish is so simple to make and flavourful it boggles the mind. Twenty minutes (I timed myself making it, LOL) and it was done before the table was set.

Another simple to make and easy on the money dish. DGD's had no cheese on it since she still doesn't like it and it tasted fine. Same dish can be made with pesto or salsa/pico de gallo with minor adjustments. Use any mild flavored melting cheese you've on hand such as Fontina, Pepper Jack, Swiss, etc.
a salad Nicoise (tons of recipes via Google; I just do it out of my head). My only caveat is to try using tuna packed in olive oil since it tastes much better for this dish. When I can't find the versions in glass jars I use Progresso's or Genova's canned version. Can't find any packed in olive oil? Drain the liquid off and add olive oil into the can, place in fridge and allow the oil time to premeate the canned goods. Generally if I do this in the morning it's ready come dinner time.
Steamed mussels. Serve a pot of them seasoned with garlic, parsley and white wine or beer for a Gallic version. Italian is much the same with the addition of tomatoes. A loaf of bread, a green salad and you're done.
Speaking of salads if you've an abundance of soft leafed herbs on hand mix them together in equal portions, make a vinegarette and serve. Parsley, chives, mint, basil, jump to mind. Nice with any grilled meat or fish.
Finally, it isn't summer on this end if I don't make a rice salad. Again I do it w/o a recipe but here's an article about the hows and whys as well as a recipe. You can make it as simple as foraging through your fridge or follow a recipe to the letter. I generally use cukes, a little radish, tomatoes, and fresh mint in addition to the canned oil packed tuna. Frozen peas defrosted via cold running water are good too.
