A Vitamix would sure make veg prep easier, Hops.
Maybe pre prep the quantities you'll use, and put in fridge for grabbing as needed. Then you clean the Vitamix less often.
We're working through a quantity of white and red Bolognese sauces right now...... SO GOOD. You can add tons of celery, zucchini, onions, carrots and I should think Tempeh would be good in that. I could eat it every day with crackers..... I try to eat it on it's own.
I cooke the veg down on it's own, then deglaze with the wine..... we had Pino G so I used that, twice, recently..... makes a delicious sauce. You mentioned using butter..... maybe add some dairy or non dairy..... we used cream then add butter to taste as we plate.
I guess you could serve the white Bolognese with fish.... would be delicious. The red wine version would be good with mushtroom steaks.... love mushrooms in this house. Making a large pot, of each, means we get to freeze some for later...... easy and happy grab when things are busy.
Another yummy recent cook was white chili. I followed a recipe then put tons more beans into the mix than called for. It's delicious and there's so many ways to enjoy it...... breakfast eggs, big salad with all the taco condiments, on it's own, warm with a bit of crushed up corn chips and avocado.... with rice..... it's just tasty and not difficult to make, IMO.
I hope you do make that little chopped salad with the Vitamix, Hops. Red wine vinegar, olive oil, Nature's Seasoning and whatever acid you have.... I love lemons or limes equally..... it's perfect as a side dish with lentils. If I add fresh tomatoes to that salad, I usually just toss in some grape tomatoes as I serve, bc they get mushy and break down faster than the cucumber, radishes and carrots in the fridge. I can have leftovers for days if I don't add chopped tomatoes to the batch. Oh.... lots an lots of fresh flat leaf parsley..... so darned good and fresh.
Adding quinoa to that salad, maybe changing up the veggies, is another good option for cold summer salads with some protein.
