I let frozen veggies defrost a bit, then only sautee, or micro, just enough to heat up.
A common work lunch is whole grain-usually rice, brown or white, maybe pasta, that's already made. (I'll freeze grains) with veggies straight from the freezer, then topped with something like a sauce made from peanut butter thinned with water or non dairy milk and hot sauce. Or curry powder, or just a bit of margarine and seasoning, maybe topped with nuts. I don't even put in the fridge, by lunch it's fine and takes a couple minutes in the micro
I never follow the cooking directions on frozen vegetable bags. Like for a stir fry, a little thaw and right in the pan, or at the end of cooking pasta- I'll scoop out the pasta from the water, leave about an inch in the pot and heat up the frozen broccoli. Then I just use a lot of nutritional yeast, a bit of miso, lemon juice and sauteed veggies like onion mushroom and garlic and pepper, spinach. This is dinner and tomorrow lunch
Don't let the perfect be the enemy of the good
